Abstract:	The potential of integrated optical microcavities for use in enhanced optical spectroscopy has been studied. These devices can sustain high morphological enhancement of optical field due to excitation of high-Q whispering gallery modes (WGM’s). Estimations performed show that a local field in a microcavity can be increased by 2-4 orders of magnitude. A gain of 103 ¸ 107 in detected Raman or fluorescent signal of a molecule put on top of the microcavity can be expected. We have fabricated high-Finesse integrated optics cylindrical microcavities that indeed provide fairly high enhancement of the optical field. The results obtained demonstrate feasibility of the microcavity-based device for optical spectroscopy.
