A process of mode matching in a chaotic speckle pattern without reference beam responsible for the formation holographic grating was studied experimentally and theoretically. Our approach based on measuring amplitudes phases Hermite-Gauss (HG) Laguerre-Gauss (LG) modes formed by radiation multimode gradient fiber. The hologram spatial light modulator using fiber model while taking into account ...

In this paper the effects of transmittance, dispersion angle and diffusion length on the quantum efficiency of solar cells (QESC) have been simulated and investigated. Optical path technic is used for simulation. The results show that base thickness, diffusion length, dispersion angle, number of optical confinement path and transmission angles have an extremely effects on the QESC. Simulation r...

We are reporting on easily-made, flexible, wearable, and stretchable holographic gratings for tunable distributed-feedback lasers. The laser device is formed by the integration of a reflection volume phase grating in flexible substrate. recorded photopolymerizable mixture using optical holography. photopolymerizing material new compound derived from recently developed which based largely haloal...
