Paper Abstract

The quest for low power and high frequency electro-optical modulator has been one of the important endeavors in microwave photonics. The advent of microdisk electro-optic modulator created a new domain in optical modulator and photonic microwave receiver design by exploiting the unique properties of high quality (high-Q) Whispering-Gallery Mode (WGM) optical cavities. High-Q crystalline WG cavities were the first devices used as compact and low power resonant electro-optical modulators and gradually semiconductor and polymer based microdisk and microring modulators emerged from this core technology. Due to its small size, high sensitivity and limited bandwidth, originally microdisk modulator was developed with the objective of replacing the conventional microwave wireless receiver frontend with a sensitive photonic front-end. Later it was shown that the electro-optic microdisk modulator could also function as a microwave frequency mixer in optical domain. Starting from fundamentals of resonant electro-optic modulation in high-Q WGM cavities, in this paper we review the development of high sensitivity microdisk modulators and the recent progress toward more efficient modulation at higher frequencies. Next related topics such as singlesideband modulation, all-dielectric photonic receiver, and semiconductor microring modulators are briefly discussed. Finally, photonic microwave receiver configurations that employ high-Q optical resonance for modulation, filtering and mixing are presented. We will show that high-Q optical resonance is one of the promising routes toward the general idea of an all-optical microwave receiver free of high frequency electronic transistors, mixers and filters.
