Novel whispering-gallery resonators for lasers, modulators, and sensors

This report describes novel whispering-gallery resonators with added physical properties, including a micro-toroidal cavity with large free spectral range ~4OOGHz and finesse >104, a lithium niobatespherical cavity in a high-efficiency X-band electro-optic modulator, and an immersed silica microsphere as high-resolution chemical sensor.
