Paper Abstract

Passive ring cavities are now treated as the most promising sensitive elements for cheap and technologically simple micro-optical gyros for mass production. Usually the single-mode planar waveguides are considered to be the only possible technology for such devices’ implementation. However, our analysis shows that in some cases the confocal ring cavity, characterized by the degeneration of transverse modes, can be the better alternative for such a device technology. We consider possible advantages and disadvantages of such an approach, its limitations, and technology prospects.
