摘要： Systems and methods are disclosed herein to provide various optical techniques. For example, in accordance with an embodiment of the present invention, a pulse position modulation discriminator architecture is disclosed for discriminating temporal positions of PPM-encoded optical pulses by converting them from time modulated to frequency modulated signals. As another example, time division multiplexed optical signals may be translated to wavelength division multiplexed optical signals. One or more of the architectures disclosed herein may be implemented, for example, to provide PPM to FM or time to wavelength conversion for receiver or transmitter applications.

摘要： An optical pulse position modulation receiver relying on the gain dynamics in a semiconductor optical amplifier (SOA). Optical PPM signal pulses and periodic optical clock pulses at a different frequency and/or polarization than the signal pulses are coupled into an SOA. Due to the high optical power of the clock pulses, the SOA gain will drop to a small value after each clock pulse. The SOA will then amplify each signal pulse that follows the clock pulse, and the gain will depend on the delay between the signal pulse and the preceding optical clock pulse. The optical output of the SOA can then be converted to an electrical signal by a photodetector.

摘要： An optical top-hat pulse generator comprising a polarization-maintaining fiber loop and controlled by solitons. A polarization-maintaining coupler launches a continuous wave optical signal into the fiber loop along a principal axis of the fiber loop. Another coupler launches a control pulse into the fiber loop along another orthogonal principal axis. The fiber loop may consist of a plurality of sections of polarization-maintaining fiber spliced together so that the principal axis of one section aligns with the orthogonal principal axis of an adjacent section and the length of each individual section is chosen to achieve equal in magnitude, but opposite in sign group delays between the continuous wave optical signal and the control pulse.
