摘要： A wavelength independent multi-section optical coupler having at least three optical couplers, and at least two differential phase cells. Each optical coupler has two waveguides forming a coupling region having a net coupling value. The coupling value for each coupling region of the at least three optical couplers is different than the coupling values of the other two coupling regions. Each differential phase cell connects adjacent ones of said optical couplers. Each differential phase cell causes a differential phase shift in light signals traversing between the optical couplers, wherein the differential phase shifts of the differential phase cells, and the coupling value for each coupling region are chosen so as to minimize wavelength, and fabrication sensitivity of said wavelength independent multi-section optical coupler for a designed power splitting ratio.

摘要： An optical receiver utilizes differential quadrature phase-shift keying (DQPSK) demodulation and electrical crosstalk rejection to relax requirements on filter misalignment with a carrier signal and to enable electronic polarization demultiplexing of optical signals. The optical receiver uses additional polarization state information when performing differential phase measurements on the optical signals. This provides information that ensures that data can be recovered by the optical receiver regardless of the state of polarization introduced during transmission of the optical signals. The optical receiver over samples the optical signals, which enables electrical polarization demultiplexing of the optical signals. The electrical crosstalk rejection provides a tracking algorithm that isolates received optical signals, and reduces crosstalk between data sequences.
