Photonic Frequency Synthesis and Control with Whispering Gallery Mode Microresonators

摘要

Dielectric microresonators with whispering-gallery modes (WGMs) may possess high Q-factors (108 - 1010), small size, and small mode volumes. Nonlinear and/or tunable WGM resonators are useful in many fundamental and practical applications. We report here on experimental and theoretical studies of electro-optical tunability of WGMs in high-Q monolithic lithium niobate resonators and applicability of such resonators for light modulation and filtering. Properties of an optoelectronic microwave oscillator (OEO) based on an WGM LiNbO{sub}3 resonator are discussed.
