摘要： Temperature compensation of a wavelength-division-multiplexed (WDM) passive optical network (PON) communication system uses power measurements from each of it remote nodes (RNs) to adjust the frequency of an associated multifrequency laser (MFL). Changes in the power level at each RN caused by frequency drift of its waveguide grating router (WGR), due to changes in the WGR temperature, is determined by monitoring the power level received at each RN and corrected by appropriate changes in the temperature of the associated MFL. The WGR uses one output port (e.g., channel 1) which is looped-back through the WGR a second time to increase the temperature sensitivity of the power measurements. A temperature-control algorithm controls the temperature of the MFL as a function of changes in the received power at the WGR.

摘要： A polarization compensated waveguide grating router is formed by reducing the thickness of the cladding material deposited over segments of waveguide cores to be on the order of the height of the vertical extension of the optical field of the waveguide. The resulting "air-patch" segments increase the birefringence in the patch segments of the waveguides. By using an air-patch length which is inversely proportional to the length of each waveguide, the correct phase relationship can be maintained between the different waveguides to produce an InP-based router which is polarization independent.

摘要： A wavelength division multiplex (WDM) cross-connect architecture that can selectively cross-connect, at a wavelength granularity, wavelength channels from any of a plurality of input WDM optical facilities (e.g., fibers) to any of a plurality of output WDM optical facilities. The architecture is based on multi-wavelength modules, which are capable of routing simultaneously N wavelengths. The number of required modules scales only with k2 or less (i.e., k2 modules with N complexity), where k is the number of input/output fibers. The significant reduction in complexity is traded for a decrease in blocking performance; one of the disclosed architectures is strictly non-blocking in the space domain and rearrangeably non-blocking in the wavelength domain, whereas two others are rearrangeably non-blocking in both the wavelength and space domain. Since the wavelength channels are optically multiplexed in the interconnection fibers, only a small number of optical amplifiers are needed to compensate for the inevitable transmission loss in the interconnection fabric.

摘要： A waveguide grating multifrequency receiver (MFR) is described with low polarization sensitivity. Polarization insensitivity is achieved using our polarization diversity scheme in which the TM polarized signal component of the unpolarized received input signal is converted to a second TE polarized signal and both TE polarized signals are made to share a common waveguide grating router and photodetectors. The MFR may be implemented using integrated optical preamplifiers and detectors in indium phosphide (InP).

摘要： A method for forming a reflective digitally tunable laser using selective area epitaxy is disclosed. The laser comprises passive waveguides and a plurality of optical amplifiers. The waveguides and optical amplifiers are formed by depositing multiple quantum wells having a suitable bandgap. According to the method, the multiple quantum wells forming both the passive waveguides and the optical amplifiers are deposited simultaneously using a dielectric mask. The mask comprises dual, rectangularly-shaped strips of dielectric material, spaced to form a gap. The multiple quantum wells grown in the gap are suitable for use as optical amplifiers, and those grown outside of the gap are suitable for use as passive waveguides.

摘要： An optical amplifier is adapted to cancel the Raman gain of an optical transmission path that degrades those optical signals occupying the low end of the bandwidth such that the power is transferred from the latter signals to the optical signals occupying the high end of the bandwidth. More specifically, the optical amplifier adjusts the gain that it applies to the optical signals so that it favors the signal components at the low end of the bandwidth.
