Abstract:

Multiplexing of the Linac Coherent Light Source beam was demonstrated for hard X-rays by spectral division using a near-perfect diamond thin-crystal monochromator operating in the Bragg geometry. The wavefront and coherence properties of both the reflected and transmitted beams were well preserved, thus allowing simultaneous measurements at two separate instruments. In this report, the structure determination of a prototypical protein was performed using serial femtosecond crystallography simultaneously with a femtosecond time-resolved XANES studies of photoexcited spin transition dynamics in

Abstract:

Semiconductor superluminescent light-emitting diodes (SLEDs) have emerged as ideal and vital broadband light sources with extensive applications, such as optical fiber-based sensors, biomedical sensing/imaging, wavelength-division multiplexing system testing and optoelectronic systems, etc. Self-assembled quantum dots (SAQDs) are very promising candidates for the realization of broadband SLED due to their intrinsic large inhomogeneous spectral broadening. Introducing excited states (ESs) emission could further increase the spectral bandwidth. However, almost all QD-based SLEDs are limited to t

Abstract:

Dual-comb spectroscopy as an emerging tool for spectral analysis has been investigated in a wide range of applications, including absorption spectroscopy, light detection and ranging, and nonlinear spectral imaging. Two mutually coherent combs facilitate high-precision, high-resolution, and broadband spectroscopy. Recently, dual combs generated from a single cavity have become compelling options for dual-comb spectroscopy, enabling huge simplification to measuring systems. Here, we review the progress of single-cavity dual comb lasers in recent years and summarize the distinctive advantages of

Abstract:

X-ray free-electron laser sources such as the Linac Coherent Light Source offer very exciting possibilities for unique research. However, beam time at such facilities is very limited and in high demand. This has led to significant efforts towards beam multiplexing of various forms. One such effort involves re-using the so-called spent beam that passes through the hole in an area detector after a weak interaction with a primary sample. This beam can be refocused into a secondary interaction region and used for a second, independent experiment operating in series. The beam profile of this refocu

Abstract:

We consider application of the discrete Fourier transform-spread orthogonal frequency-division multiplexing (DFT-spread OFDM) technique to high-speed fiber optic communications. The DFT-spread OFDM is a form of single-carrier technique that possesses almost all advantages of the multicarrier OFDM technique (such as high spectral efficiency, flexible bandwidth allocation, low sampling rate, and low-complexity equalization). In particular, we consider the optical DFT-spread OFDM system with polarization division multiplexing (PDM) that employs a tone-by-tone linear minimum mean square error (MMS

Abstract:

In this work, high-speed transmission over the long-haul optical channel using orthogonal frequency division multiplexing (OFDM) was investigated. Furthermore, we recommend mixing polarization division multiplexing (PDM) with coherent OFDM (CO-OFDM) and quadrature amplitude modulation (16-QAM) to improve spectral efficiency (SE) while transmitting over a wavelength division multiplexing (WDM) system. An 800 Gb/s WDM PDM-CO-OFDM-16QAM transmission system with various channel spacing of 100 GHz, 50 GHz, and 25 GHz is examined utilizing the OptiSystem (2021) version 18.0 software package over ten

Abstract:

A novel approach of building a large capacity optical correlator using VanderLugt’s matched spatial filter is introduced in which a tunable dye laser is used as the coherent light source and a rotatable diffraction grating is placed at the input object plane. While sequentially rotating the grating about the optical axis and tuning the wavelength of the dye laser, the input signal spectrum is scanned along trajectories of concentric circles at the Fourier plane. With this 2-D scanning approach, the number of matched filters that can be built at the Fourier plane is greatly increased due to the

Abstract:

A phase mask is a phase diffraction grating usually recorded in photoresist and then etched in a bulk substrate as a one-dimensional uniform and periodic surface relief pattern[1,2]. When illuminated at normal incidence with coherent or partially coherent light, the phase mask produces in its near-field self-interference between the first order diffracted beams. This interference fringe pattern will have a spatial frequency that is twice the spatial frequency of the phase mask, and will be photoimprinted in the photosensitive medium placed in close proximity of die phase mask grating.

Abstract:

This paper presents new ways in which stimulated Brillouin scattering (SBS) may be used to combine the outputs of several laser amplifiers to create a single coherent beam of high average power. The SBS produces optical phase conjugation which is characterized by (a) retroreflection of the incident beam and (b) correction of the wavefront distortions. Both properties are important for combining in the most useful manner the outputs of separate amplifiers. Three approaches to beam combining are discussed: (1) time multiplexing; (2) spatial multiplexing or phased arrays; and (3) serial combining
