Paper Abstract

Solid state optical gyrometer is a novel integrated optical gyrometer which consists of a waveguide coil fully integrated on a substrate. The planar coil design implies waveguide crossings, so called X-junction. X-junctions are loss generating. In this paper, the power loss of X-junction is simulated by beam propagation method. The relationship between the power loss and the intersection angle is illustrated, and the power coupling corresponded with the intersection angle is given. The simulation shows the power loss due to the X-junction could be neglected by increasing the intersection angle properly.
