摘要： Consistent with the present disclosure, a non-adiabatic polarization rotator is provided that can rotate the polarization of an incoming over a relatively short length. Light is supplied to the polarization rotator via a polarizer, which insures that the optical input to the polarization polarization rotator has a desired polarization. Preferably, the polarization rotator has a structure that is readily implemented with semiconductor materials and can be fabricated with known processing techniques. In addition, the polarization rotator and polarizer may include similar materials and/or layers, such that both may be readily integrated on a common substrate, such as an indium phosphide (InP) substrate.

摘要： Embodiments of the present invention provide for enhanced monitoring of optical signal characteristics of an optical signal propagating in a signal channel of a photonic integrated circuit. The optical signal characteristics can be obtained with minimal signal loss in the optical signal path and reduced RF crosstalk, while the electrostatic discharge threshold for the photonic integrated circuit is increased, due to the inclusion of a second electro-optic element electrically coupled to a first electro-optic element as part of the signal channel.

摘要： Consistent with the present disclosure, an AWG is provided that has grating waveguide groupings that extend between a first free space region and a second free space region. The difference in length (ΔL) between successive grating waveguides differs for each grouping of grating waveguides, such that, for example, the ΔL associated with a given grating waveguide grouping is not an integer multiple of any of the other grating waveguide groupings. The grating waveguide groupings direct images having relatively small wavelength differences to a given output waveguide, and each grating waveguide grouping has an associated passband, which is similar to that of the conventional AWG. Unlike the conventional AWG, however, multiple grating waveguide groupings are included in the same AWG, such that the spectra associated with the grating waveguide groupings combine to provide a transmission characteristic having a passband that is greater than any individual passband. Accordingly, even if the optical signal wavelengths vary or are offset from the center wavelength of the passband, such wavelengths may still be transmitted with less loss.

摘要： Pairs of distributed feedback (DFB) lasers are provided on a substrate. An arrayed waveguide grating (AWG) is also provided on the substrate having input waveguides, each of which being connected to a corresponding pair of DFB lasers. The wavelengths of optical signals supplied from each pair of DFB lasers may be spectrally spaced from one another by a free spectral range (FSR) of the AWG. By selecting either a first or second DFB laser in a pair and temperature tuning to adjust the wavelength, each pair of DFB lasers can supply optical signals at one of four wavelengths, pairs of which are spectrally spaced from one another by the FSR of the AWG. A widely tunable transmitter may thus be obtained.

摘要： The present invention provides a system, apparatus and method to control an optical polarization beam splitter. A portion of an optical output of the polarization beam splitter is converted into a corresponding electrical signal. The electrical signal is then provided to the polarization beam splitter as a control signal via a feedback loop. The polarization beam splitter controls a characteristic of the optical output of the polarization beam splitter in response to the received control signal. The characteristic, for example, may be controlled through thermo-optically or electro-optically. The control system may be used over a period of time to maintain the characteristic at a desired value, for example as the components of the polarization beam splitter, or other elements used in the control of the polarization beam splitter, age.
