Abstract:

Thesis (S.B.)--Massachusetts Institute of Technology, Dept. of Physics, June 2004.<br>Includes bibliographical references (p. 65-66).<br>Electromagnetically Induced Transparency (EIT) is a quantum nonlinear optical interference effect in which light at a certain frequency makes normally opaque atomic systems transparent to light at another frequency. Recent experiments in Atomic Molecular and Optical (AMO) physics demonstrated how the EIT effect can be used to store light pulses in an atomic system by coupling the light to the atomic system. One of the most elegant predictions of EIT theory is

Abstract:

At the nanoscopic level, light interacts with matter in interesting ways. Plasmonics is the study of one such interaction where light interacts with electrons at the surface of particles. The oscillation of the electrons when light interacts with them are called Plasmons and have many properties, one of which can cause nanoparticles to become "cloaked" or more precisely: transparent. The application of "cloaking" extends to sensors, solar cells and numerous other uses. We have investigated how changing the geometry of nanoparticles alters "cloaking" behaviour and have found that thicker partic

Although photonic devices have experienced a rapid development lately, there is still room for substantial improvements in performance.

This thesis presents the development of photonic microcells for use as the host for coherent optics phenomena and related applications. A photonic microcell consists of a length of hollow-core photonic crystal fibre (HC-PCF) with a gas-filled core that is spliced to conventional optical fibre at either end to seal the gas within the fibre. Towards the goal of demonstrating and assessing the coherence properties of quantum optical effects in photonic microcells, the fabrication of two types of HC-PCF is presented.

Abstract:

The recent prospect of efficient, reliable, and secure quantum communication relies on the ability to coherently and reversibly map nonclassical states of light onto long-lived atomic states. A promising technique that accomplishes this employs Electromagnetically Induced Transparency (EIT), in which a strong classical control field modifies the optical properties of a weak signal field in such a way that a previously opaque medium becomes transparent to the signal field. The accompanying steep dispersion in the index of refraction allows for pulses of light to be decelerated, then stored as a

For example, a 6 μs Gaussian pulse propagate at a velocity of ~1 km/s (to be compared with the normal velocity of 300 000 km/s).

碩士<br>國立交通大學<br>電子物理系所<br>105<br>Under the external electromagnetic field, the atom produces the coherent states and emits the radiation by the different process of transition interfering the probability of the transition of the electrons in the system. The paper mainly focuses on the analysis of the three level system and two effects under the radiation with two different frequencies and their applications which are Electromagnetically Induced Transparency (EIT) and Coherent Population Trapping (CPT).We would discuss the method of computation and analyze the variation of the property of optic

Abstract:

碩士<br>國立成功大學<br>物理學系<br>102<br>We report experimental observation of electromagnetically induced transparency (EIT) that both probe and coupling fields are π-polarized. The probe field will be absorbed strongly based on the Λ-EIT scheme of cold atomic ensemble of 87Rb due to the absence of the coupling field at one of Zeeman state. We use a pumping light to avoid this problem and restore the high transmission property of EIT. In order to observe the relation with the Doppler effect and transmission, we set the angle of the probe and coupling beams for 90 degrees, and infer the temperature of c

碩士<br>國立成功大學<br>物理學系碩博士班<br>98<br>We investigate the V-type electromagnetically induced transparency (EIT) in a multi-level system of cesium atoms at room temperature for both experimental observations and theoretical simulations. In this experiment, the frequency of the probe laser is locked at the selected cesium D2 transition,|6 S1/2, F=3＞ to |6 P3/2, F=4＞, and the coupling laser scans across the hyperfine transition,|6 S1/2, F=3＞ to |6 P3/2, F=2,3,4＞. The transmission of the probe beam can be detected while changing the frequency of coupling laser. The numerical simulations of each probed

Abstract:

碩士<br>國立成功大學<br>物理學系碩博士班<br>100<br>The hyperfine structure of 87Rb 9S1/2 and 5D5/2 states was investigated using cascade-type electromagnetically induced transparency (EIT) in this thesis. The theoretical modeling the transparency of a weak probe laser beam at 780.2 nm (5S1/2→5P3/2) under the interaction with a strong coupling laser beams at 565 nm or 776 nm (5P3/2→9S1/2 or 5P3/2→5D5/2) was obtained by solving the steady state solutions of optical-Bloch equations. This transparency is due to the quantum interference of the atomic wavefunctions under the photon-atom interactions. To carry out t

Abstract:

博士<br>國立清華大學<br>物理系<br>101<br>The thesis is to study the quantum properties of optical fields, squeezing and entanglement, based on the electromagnetically induced transparency (EIT) schemes. Under the low-intensity approximation, we study the quantum entanglement between two fields after travelling through a Lambda-type EIT medium, and find that some particular conditions satisfies non-separable criterion. Extending the single-Lambda EIT system to multi-Lambda EIT system, one has more degree freedom to study quantum properties of light. By controlling the relative strengths among coupling fie
