DPSK Demodulator
-
Optical differential-phase shift keying (DPSK) provides a desired modulation format that offers high receiver sensitivity, high tolerance to major nonlinear effects in high-speed transmissions, and high tolerance to coherent crosstalk. In DPSK, data information is carried by the optical phase difference between adjacent bits. For direct detection of DPSK signal (by conventional intensity detectors), a DPSK demodulator is needed to convert the phase-coded signal into an intensity-coded signal.

40Gb/s DQPSK Receiver
-
The integrated DQPSK receiver incorporates an optical phase demodulator (delay-line interferometer or DLI) with 2 pairs of balanced photo-diodes and 2 linear TIAs into a single butterfly package. Compared with the currently available discrete solution in which a separate DLI and a separate receiver are used, the integrated DQPSK receiver eliminates labor intensive fiber routing and coupling (between the DLI and the balanced receiver) as well as the skew control. Moreover, the integrated DQPSK receiver offers a smaller footprint suitable for today’s demanding high speed transponder applications.

DQPSK Demodulator
-
Differential Quaternary Phase-Shift Keying (DQPSK) is the four-level version of DPSK. DQPSK transmits two bits for every symbol (bit combinations being 00, 01, 11 and 10) and has an additional advantage over conventional binary DPSK. DQPSK has a narrower optical spectrum, which tolerates more dispersion (both chromatic and polarization-mode), allows for stronger optical filtering, and enables closer channel spacing. As a result, DQPSK is the only modulation format which allows processing of 40Gb/s data-rate in a 50-GHz channel spacing system.
