Abstract
The operational principles of passive and active LiNb03 waveguide crossings are outlined. The radiation losses and crosstalk in large-angle passive waveguide crossings are calculated using the beam-propagation method. A detailed electrode analysis of an electrooptic X-switch is presented and compared with that of a directional coupler switch.Prospective applications of waveguide crossings are listed. As an example, the parameters of an integrated 4x4 switching array with 16 X-switches are presented.© (1986) COPYRIGHT SPIE--The International Society for Optical Engineering.
