WebAug 1, 2024 · Phase flicker has become an important performance parameter for the liquid crystal on silicon (LCOS) devices. Since the phase response of the LCOS device cannot be measured directly, it is usually derived from the intensity response of the modulated light beam when the LCOS device was placed between a pair of crossed polarisers. However, … WebFabricated in 22-nm FDSOI, the prototype occupies a compact area of 0.01mm 2 and achieves PN corner of 70kHz, PN of −110dBc/Hz at 1MHz offset, figure-of-merit (FoM) of …
