摘要： An optical-to-optical wavelength converter for converting a plurality of optical bits from a first wavelength in a first wavelength band to a second wavelength in a second wavelength band. The optical-to-optical wavelength converter employs a directional coupler. The directional coupler includes at least one optical element having an index of refraction, which changes in response to optical power substantially in the first wavelength band.

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： The present invention provides a system, apparatus and method to maintain the polarization state of an optical signal propagating within a photonic integrated circuit, or from a first photonic integrated circuit to a second photonic integrated circuit. According to various embodiments of the invention, an optical circuit is provided which includes an optical coupler configured to accept a first optical signal on a first input and a second optical signal on a second input, the second optical signal having a polarization state. The optical coupler may combine the first and second optical signals into an optical output signal. A principle axis of a first end of an optical fiber is may be configured to align with the polarization state of the second optical signal, such that a polarization maintaining connection is established. The polarization state may be a TM polarization state, a TE polarization state, or another polarization state. The optical circuit may include birefringent structures, such as birefringent waveguides and birefringent wavelength selective couplers, to further maintain the polarization of optical signals propagating through the photonic integrated circuits.

摘要： A multifrequency laser (MFL) eliminates nonlinearities produced in the "shared" waveguide of the MFL laser (the section in which all the lightwaves from all the lasers pass) by either making the shared waveguide as short as possible to mimimize the production of mixing product signals or using a channel spacing that is unequal such that any mixing product signals formed from the multifrequency optical laser signal do not overlap in frequency with any of the signals of the multifrequency optical laser signal.
