Abstract

Multimode waveguide couplers using widely spaced access waveguides have showed good performance, but carries the penalty of increased device length. This can be detrimental to deeply etched, strongly confining rib waveguides. A theoretical and experimental study on ultra-compact couplers were conducted by implementing in these structures small separations and large branching angles of the access waveguides. A computer model is utilized to examine the effects of employing large branching angles of the access guides and to describe mode fields which were effectively x-y separable. The results of an experimental study on quantum well Mach Zehnder directional switch showed good correlation with the model predictions.
