摘要
We designed a microwave (MW) photonics phase shifter, consisting of a Fabry-Perot filter, a phase modulation region (PMR), and distributed Bragg reflectors, in a silicon-on-insulator rib waveguide. The thermo-optics effect was employed to tune the PMR. It was theoretically demonstrated that the linear MW phase shift of 0 - 2 pi could be achieved by a refractive index variation of 0 - 9.68 x 10(-3) in an ultrawideband (about 38GHz - 1.9 THz), and the corresponding tuning resolution was about 6.92 degrees/degrees C. The device had a very compact size. It could be easily integrated in silicon optoelectronic chips and expected to be widely used in the high-frequency MW photonics field.
