40 Gb/s DQPSK Dual Parallel Modulator

The Oclaro DQPSK(Differential Quadrature Reference Phase Shift Keying) modulator 

design is based on a dual parallel structure of two Mach-Zehnder modulators embedded 

in a Mach-Zehnder super-structure. Each internal modulator is designed to support 22 Gb/s 

signals. An integrated polarizer enables high extinction ratios as required for the DQPSK 

modulation format. High bandwidth photodiode is provided for automatic bias control.
