摘要： An apparatus and method for performing joint equalization and timing recovery in coherent optical systems. The method includes equalizing signals to generate compensated polarization signals, wherein timing error in a distorted optical signal is calculated based on one of the compensated polarization signals. The method further includes performing resampling polarization signals to correct timing offset in an optical signal based on the calculated timing error. The calculated timing error may also be used to adaptively control one or more operating parameters of an external device.

摘要： Probabilistic generation and decoding modulation symbols for use with optical communication. Codewords are generated using combinations of symbols from a modulation symbol alphabet, and each type of modulation symbol is sequentially generated using a hardware efficient combination generator that performs as a virtual lookup table (LUT). Likewise, decoding can be performed by sequentially identifying locations of individual modulation symbols within the received codeword.

摘要： An electronic driver circuit for use with a modulator such as a segmented Mach-Zehnder Modulator (MZM) is provided. The electronic driver circuit includes a first delay buffer implemented as a first complementary metal-oxide-semiconductor (CMOS) inverter and a second delay buffer implemented as a second CMOS inverter. The second CMOS inverter follows the first CMOS inverter and has a second gate width smaller than a first gate width of the first CMOS inverter. The first CMOS inverter is configured to produce a first delayed electrical signal from a received electrical signal and the second CMOS inverter is configured to produce a second delayed electrical signal from the first delayed electrical signal produced by the first CMOS inverter.
