摘要： An optical communications subsystem is proposed to permit the multiplexing of multiple, parallel electronic data streams onto a serial, very high speed optical data channel. The subsystem may also be used to generate programmable ultrafast optical data words for the testing of optical components, and system performance testing of very high speed data transmission systems. The key device component, based on a modified arrayed waveguide grating structure, is directly integratable with a high-speed optoelectronic modulator array in a simple, cost effect, and manufacturable configuration. Pulse spacings as small as 1 picosecond have been demonstrated corresponding to an effective data rate of up to one terahertz. An integrated optical pulse generator is configured to receive a laser light input and output an optical pulse train. Direct space-to-time pulse shaping and optical pulse train generation is achieved by use of an arrayed waveguide (AWG) that is double-passed. A mask is utilized for time domain pulse shaping that is employed after a single pass through the arrayed waveguide. In the case of an optical data/word generator, a spatially patterned mask translates spatial data, for example representing binary data or a binary word, of the mask to the output optical pulse train. The arrayed waveguide (AWG) system has waveguide ports that double as inputs and outputs, and provides direct space-to-time pulse shaping of a single, short pulse laser/optic signal. Direct optical access to individual guides in the waveguide array allows one to control the light intensity in each guide and therefore control the output pulse intensities with a one-guide one-pulse effect.

摘要： An apparatus and method for correcting for the polarization mode distortion of an optical signal is described. The optical data signal to be transmitted is processed by a switch configured to place the signal into a plurality of polarization states on a periodic basis. At the receiving end of the system, a portion to the signal is coupled to a polarimeter and the wavelength-dependent state of polarization (SOP) of the received signal determined for the plurality of polarization states imposed on the transmitted signal. The data for two of the transmitted polarization states is selected to be used as the basis for correcting the SOP so as to compensate for the wavelength dependence thereof. The corrections may be applied in an optical pulse shaper.

摘要： An optical processing method includes: receiving an optical signal from an optical system, wherein the optical signal is distorted by frequency-dependent polarization effects in the optical system; spatially dispersing frequency components of the distorted optical signal on a spatial light modulator (SLM); and independently adjusting the polarization transfer matrix of multiple regions of the SLM to reduce the distortion of the optical signal. A related optical processing method includes: providing a precompensation signal indicative of frequency-dependent polarization effects in a downstream optical system; spatially dispersing frequency components of an optical signal on a spatial light modulator (SLM); and independently adjusting the polarization transfer matrix of multiple regions of the SLM to at least partially precompensate the optical signal for distortions caused by the frequency-dependent polarization effects in the downstream optical system. Another related optical processing method includes: providing a model of the frequency-dependent polarization effects; spatially dispersing frequency components of the optical signal on a spatial light modulator (SLM); and independently adjusting the polarization transfer matrix of multiple regions of the SLM based on the model to emulate the optical signal transmission.
