Abstract

Optical time division multiplexing (OTDM) is a powerful means of increasing optical network capacity while still employing relatively inexpensive low-speed electronics. The critical and limiting component in such systems is the demultiplexer that picks apart the high-data-rate optical bit stream before detection and electrical signal processing at a lower data rate. Electro-optic demultiplexing using high-speed lithium niobate waveguide devices, either 1×2 switches¹ or on/off modulators², has thus far been the most successful method for OTDM system demonstrations, although recently semiconductor modulators³ have also been used.
