Abstract:
AbstractAn overview on current trends in stimulated Brillouin scattering and optical phase conjugation is given. This report is based on the results of the “Second International Workshop on stimulated Brillouin scattering and phase conjugation” held in Potsdam/Germany in September 2007. The properties of stimulated Brillouin scattering are presented for the compensation of phase distortions in combination with novel laser technology like ceramics materials but also for e.g., phase stabilization, beam combination, and slow light. Photorefractive nonlinear mirrors and resonant refractive index gratings are addressed as phase conjugating mirrors in addition.

Abstract:
Due to the light scattering effect, it is difficult to directly achieve optical focusing and imaging in turbid media, such as milk and biological tissue. The turbidity suppression of a scattering medium and control of light through the scattering medium are important for imaging on biological tissue or biophotonics. Optical phase conjugation is a novel technology on turbidity suppression by directly creating phase conjugation light waves to form time-reversed light. In this work, we report a digital optical phase conjugation system based on off-axis holography. Compared with traditional digital optical phase conjugation methods, the off-axis holography acquires the conjugation phase using only one interference image, obviously saving photo acquisition time. Furthermore, we tested the optical phase conjugate reduction performance of this system and also achieved optical focusing through the diffuser. We also proved that the reversing of random scattering in turbid media is achievable by phase conjugation.

Abstract:
This dissertation formulates and applies a theory describing how one or two strong classical waves and one or two weak quantum mechanical waves interact in a two-level medium. The theory unifies many topics in quantum optics, such as resonance fluorescence, saturation spectroscopy, modulation spectroscopy, the build up of laser and optical bistability instabilities, and phase conjugation. The theory is based on a quantum population pulsation approach that resembles the semiclassical theories, but is substantially more detailed. Calculations are performed to include the effects of inhomogeneous broadening, spatial hole burning, and Gaussian transverse variations. The resonance fluorescence spectrum in a high finesse optical cavity is analyzed in detail, demonstrating how stimulated emission and multiwave processes alter the spectrum from the usual three peaks. The effects of quantum noise during the propagation of weak signal and conjugate fields in phase conjugation and modulation spectroscopy are studied. Our analysis demonstrates that quantum noise affects not only the intensities of the signal and conjugate, but also their relative phase, and in particular we determine a quantum limit to the semiclassical theory of FM modulation spectroscopy. Finally, we derive the corresponding theory for the two-photon, two-level medium. This yields the first calculation of the two-photon resonance fluorescence spectrum. Because of the greater number of possible interactions in the two-photon two-level model, the theoretical formalism is considerably more complex, and many effects arise that are absent in the one-photon problem. We discuss the role of the Stark shifts on the emission spectrum and show how the Rayleigh scattering is markedly different.

Full text
Abstract:
The generation of phase conjugated replicas of optical signals has been the subject of many theoretical and experimental studies. Phase conjugation of harmonic signals is a byproduct of certain nonlinear processes such as degenerate four- wave mixing and stimulated Brillouin scattering. Although conjugation of steady signals is well established, the possibility and the effectiveness of conjugating unsteady signals remain largely unexplored. When the envelope of an optical signal varies, new physical phenomena in the conjugation process arise. As previously shown,1 dispersion in the conjugation process distorts the phase conjugate replica of a pulsed signal. Distortion appears even if the response of the medium to the applied optical signal is instantaneous.

Full text
Abstract:
Polyacetylene is a long linear, chainlike material whose optical properties at visible wavelengths arise from the motion of the π-electrons along the bonds that connect the sites. The nonlinear optical properties of polyacetylene materialize from two anharmonic electronic interactions: (1) the π-electrons interact with the phonons and (2) they interact with each other through their Coulomb repulsion. The motion of the π-electrons driven by an optical field were described within a classical framework and the third-order optical susceptibility associated with phase conjugation was determined. The wavelength (λ) has dependence on the nonlinear optical susceptibility; two peaks coincide with a resonant response. A low frequency peak in the vicinity of 1.2 µm reflects a two-photon resonance process and arises from the Coulomb repulsion. A high frequency peak at 0.6 µm is the single photon resonance and arises from both the Coulomb repulsion and the electron phonon coupling.

Full text
Abstract:
Phase contrast imaging by the backward passage of a phase-conjugate beam through a phase plate that was used to produce the original phase distorted beam depends on the phase conjugate of the original field passing back through the specimen after the specimen has been shifted. We demonstrated this previously using self-pumping in barium titanate to produce the phase-conjugate field and a mechanical means to shift the plate. The intensity images show the gradients of plate optical thickness with respect to the shift direction of the specimen’s optical thickness.1 We note that an image should also result if the slide remains stationary but component elements of the specimen move. Taking advantage of this last we have developed a microscope which shows dynamic processes within biological phase objects. The stationary elements on the slide do not show up; the image shows only those elements that move. The device includes a stage of digital processing which removes coherent artifacts and also adds gradients in intensity of moving elements in the bright field intensity image.

Full text
Abstract:
In optical phase conjugation (OPC) systems, the third-order dispersion (TOD) of optical fibers and the nonlinear resonance at well-defined signal sideband frequencies called sideband instability (SI) mainly limit the transmission performance. We present for the first time a complete theoretical analysis of sideband instability (SI) that occurs when two kinds of fibers with different characteristics are concatenated to form a dispersion-managed fiber link. We find that the magnitude of the SI gain reduces with the increase in strength of dispersion management. Next, we focus on the fiber link using the combination of standard single-mode fiber (SMF) and reverse dispersion fiber (RDF), which is widely used for simultaneously compensating second-order dispersion (SOD) and third-order dispersion (TOD). By computer simulation, it is shown that, in wavelength-division-multiplexed (WDM) systems, SI still induces significant degradation in channels located at frequencies where SI induced from other channels arises.By re-allocating the channel frequency to avoid the SI frequency, the transmission performance is improved significantly. Then we propose for the first time, a scheme for simultaneous suppression of both TOD and SI in OPC systems using a higher-order dispersion-managed link consisting of SMFs and RDFs. Computer simulation results demonstrate the possibility of 200-Gbit/s transmission over 10,000 km in the higher-order dispersion-managed OPC system, where the dispersion map is optimized by our system design strategies.

Full text
Abstract:
We study four methods: the zero-dispersion wavelength (ZDWL) transmission, the dispersion management, the optical soliton transmission, and the midway optical phase conjugation (OPC), for upgrading installed electronic repeater-based optical fiber transmission system to optically amplified system. We derive the optimum design rules for each scheme to achieve the maximum transmission data rate. The 1,318-km-long Thailand-Malaysia (T-M) submarine fiber-optic transmission system is used as the system model. Firstly, we give the basic knowledge about fiber characteristics and their effects to signal propagation, and review the concepts of four upgrading schemes. Then, the numerical simulation is used for studying the signal distortion induced from the third-order dispersion and the Kerr effect in ZDWL transmission system. When the ZDWL transmission is employed to upgrade the T-M system with our optimum design guidelines, the possibility of increasing data rate from 560 Mbit/s to 80 Gbit/s is shown. For the dispersion management, the transmission data rate can be extended to 100 Gbit/s for single channel, and to 6 x 10 Gbit/s for multi-channel wavelength division multiplexing. However, when the soliton scheme is employed to improve the system performance, the numerical result shows the possibility of increasing data rate only to 20 Gbit/s because of nonlinear signal distortions. The highest data rate in this study is obtained from the system upgrading using the midway OPC. By following our design strategies, the possibility of increasing to 200 Gbit/s is numerically shown.
