Characteristics of an Integrated Optics Ring Resonator.
Abstract
A ring resonator 4 cm in diameter was fabricated and tested for sensing applications. A finesse of four was measured, and agreed with measured coupling efficiency and losses. Techniques have been developed to reduce the loss and from our measurements we predict that a finesse of more than 20 should be easily achievable in an interferometer 4 cm in diameter. This device has a wide variety of applications from temperature and wavelength sensing to inertial rotation sensing. Further refinements which will produce a high finesse resonator are the fabrication of a single mode ring and using specially prepared optical glass substrates. Operation at wavelengths longer than 0.63 micron will also improve the performance. (Author)
