Abstract

Compact integrated optical circuits for signal routing and signal processing are currently the subjects of much active research. Multimode interference (MMI) couplers are widely used as splitters and combiners since they possess the desirable attributes of small size, low excess loss, well- defined slitting, dimensional tolerance and ease of fabrication. Recently there has been renewed interest in employing MMI devices within Mach-Zehnder structures to achieve splitting and switching functions. However, the extent of the switching capabilities achieved so far has been quite limited. This paper highlights how the switching capabilities of these Mach-Zehnder switches can be extended and presents design techniques for this type of photonic switch.
