High-strain InGaAs/GaAs quantum well grown by MOCVD ... , V/III ratio, and growth rate on PL characteristic are investigated. It is found that the growth temperature and V/III ratio have strong effects on the peak wavelength and PL intensity. The full-width at half-maximum (FWHM) of PL peak increases wit
Using fence pulses to suppress stimulated Raman scattering effec... ... ) effect is difficult to suppress. We propose a method using fence pulses (FPs) to suppress the backward SRS by inhibiting the growth of the intensity of electron plasma waves. Based on our simulation, the FPs can weaken SRS effect in the LPI effectively.
Sample indexed spatial orthogonal frequency division multiplexin... ... to achieve better spectral efficiency in wireless channels. Asymmetrically clipped optical OFDM (O-OFDM) and DC-biased O-OFDM are two well-known O-OFDM techniques suitable for intensity-modulation direct-detection optical systems. In this work,
Generation and propagation of partially coherent vortex beams ... of correlation property of partially coherent vortex beams on intensity distribution. The correlation property of partially coherent vortex ... charge and propagation distance of vortex beams on the intensity are also studied. Experiment results are cons
Experimental study of unidirectional excitation of SPPs by binar... ... gold film, thus avoiding the challenge of modulating nanostructure in its depth. It is shown that SPPs can be unidirectionally and effectively excited at normal incidence. The SPP intensity and asymmetric excitation ratio, which are two key figure-of-me
Fresnel hologram reconstruction of complex three-dimensional obj... ... (CS) is presented. The hologram is synthesized from a color image and the depth map of the 3D object. With the depth map, the intensity of the color image can be divided into multiple slices, which satisfy the condition of the sparsity of CS. Thus, the ...
Practical high-speed light source for decoy-state quantum key di... ... , the signal-state and the decoy-state pulses are prepared with identical pulse duration of 25 ps and similar spectral characteristics, avoiding the eavesdropper's attack by temporal and spectral analysis. The intensity fluctuation of the light source is
Coherent X-ray mirage: discovery and possible applications In the far field of the intensity distribution of the beam delivered by a two-stage transient–collisional excitation X-ray laser (XRL), a non-expected interference pattern that is stable from shot to shot has been discovered. It is demonstrated that the ...
Irradiation uniformity at the Laser MegaJoule facility in the co... ... shock ignition scheme providing the energy gain and an estimation of the increase of the peak power due to the reduction of the photon penetration expected during the high-intensity spike pulse. In the second part, we considered a Laser MegaJoule confi
Ion motion effects on the generation of short-cycle relativistic... ... pulse modulated by ion motion is sharper compared with the case of the electron shutter only. In this study, the ions further modulate the short-cycle pulses transmitted. A 3.9 fs laser pulse with an intensity of 1.33×1021 W cm-2 is generated by prope
