In this paper we discuss theoretical aspects of achieving ultrahigh Q-factors in crystalline whispering gallery mode (WGM) resonators as well as peculiarities of parametric frequency conversion, low threshold parametric oscillations based on degenerate four-wave mixing, photorefractivity, and thermo-optical instabilities observed in the resonators.

We report on fabrication of ultrahigh-Q crystalline optical whispering gallery mode (WGM) resonators via mechanical polishing. The maximum Q-factor achieved at room temperature exceeds 2/spl times/10/sup 10/. We discuss strong nonlinear behavior of the resonators and propose several devices based on the resonators. We have studied WGM resonators fabricated of calcium fluoride and few other crystals and measured their quality factors. High optical Q-factor was obtained due to several nonlinear optical effects. Two of them are instability due to strong thermal nonlinearity and optical oscillations based on four wave mixing.

Spectroscopic photodetectors have been fabricated in a standard CMOS process. These photodetectors are designed to distinguish between two different fluorescent markers. They have applications in nucleic acid analysis, cell-based biosensors and tissue based-biosensors.

The diffraction limit to light microscope resolution, which was seen as an impassable barrier for a century, has recently been broken. Structured illumination light in combination with nonlinear phenomena allow theoretically unlimited resolution.

Novel approaches to obtain compact, high-speed, low-voltage modulators using circular microresonators are presented. Two different mechanisms, free carrier injection and depletion width modulation are considered. Frequency 3 dB bandwidths of over 8 GHz are achieved at modulation voltages less than 1V.
