摘要：
A new differential phase-shift-keyed demodulator is disclosed which can achieve signal demodulation at different wavelengths on ITU grids without requiring active thermal tuning. In accordance with another aspect of the invention, a low-crosstalk demodulator is disclosed which reduces channel leakage by placing neighboring channels at non-optimal interference positions. A demodulator in accordance with the invention may be deployed in a WDM optical system.
