Thermo optical phase shifter
WebbMentioning: 18 - Uncooled infrared detectors have enabled the rapid growth of thermal imaging applications. These detectors are predominantly bolometers, reading out a pixel’s temperature change due to infrared radiation as a resistance change. Another uncooled sensing method is to transduce the infrared radiation into the frequency shift of a … Webb31 mars 2012 · Mizumoto et al. measured the magneto-optic phase shift for TM mode propagating in magneto-optic garnet waveguides composed of YIG and bismuth-substituted gadolinium iron garnet (Bi:GdIG) .

WebbPhase shifters based on semiconductor devices can be of the reflection or the transmission type. For reflection type design, the basic realization cell is a one-port network and the phase shift of the reflected signal is changed by the control signal. WebbFor the beam steering, thermo-optic phase shifting is used for azimuthal plane beam steering and laser wavelength tuning is used for elevation plane beam steering. The OPA structure disclosed comprises a wavelength-tunable a QCL, a 1×32 splitter, thermo-optic phase-shifters, and sub-wavelength grating emitters.
