Optical phase retardation
WebApr 16, 2024 · It is also observed that the optical phase retardation factor is linearly proportional to the applied electric field. One can easily control this phase retardation factor by switching the external applied signal electrically [5,6,7,8,9,10,11,12]. The effect of amplitude modulation is successfully increased by the successive use of two Pockels ...
