    摘要： System, devices and methods are described that provide an integrated optical decombiner or optical combiner having both unamplified paths and amplified paths on which power monitoring and control may be located. A preferred multiplexing/demultiplexing optical path through the combiner/decombiner and a corresponding waveguide output/input is identified and optically coupled to a piece of fiber. Temperature control may be provided to tune an arrayed waveguide grating within the combiner/decombiner and minimize wavelength drift therein. Integrated power monitoring may be employed on one or more of the amplified waveguide paths to ensure that a preferred power level or range is maintained on an optical signal.

    摘要： A dual output laser source provided on a substrate outputs light from a first and second output. A portion of the light generated by the laser is supplied to a first modulator via the first output. A second portion of the light generated by the laser is supplied to a second modulator via the second output. The first modulator is provided on the substrate and generates a first modulated signal. The second modulator is also provided on the substrate and generates a second modulated signal. Each output of the laser is used to provide continuous wave light sources to components on photonic integrated circuit.

    摘要： Consistent with the present disclosure, an arrayed waveguide grating (AWG) is provided that includes first inputs and second inputs. Each of the first inputs receives a corresponding one of a plurality of first optical signals, each of which has a corresponding one of a plurality of wavelengths. Second inputs are also provided, such that each second input is preferably provided between two adjacent first inputs. Each of the second inputs receives a corresponding one of a plurality of second optical signals, and each of the second plurality of optical signals has a corresponding one of those wavelengths. Each of the first plurality of optical signals, however, has a first polarization and each of the second plurality of optical signals has a second polarization different than the first polarization. Since the first optical signals are supplied through AWG inputs that are offset from the inputs that receives second optical signals, the first optical signals are supplied at a first AWG output that is spaced from a second AWG output that supplies the second optical signals. The second optical signals are supplied through the second output even though the second optical signals have the same (or substantially the same) wavelengths as the first optical signals. Accordingly, a single AWG may be provided to multiplex both first and second optical signals, thereby simplifying PIC design.

    摘要翻译： 根据本公开，提供了包括第一输入和第二输入的阵列波导光栅（AWG）。 每个第一输入接收多个第一光信号中的相应的一个，每个第一光信号具有多个波长的对应的一个。 还提供第二输入，使得每个第二输入优选地设置在两个相邻的第一输入之间。 每个第二输入接收多个第二光信号中的相应一个，并且第二多个光信号中的每一个具有这些波长中的相应一个。 然而，第一多个光信号中的每一个具有第一偏振，并且第二多个光信号中的每一个具有不同于第一偏振的第二偏振。 由于通过从接收第二光信号的输入偏移的AWG输入提供第一光信号，所以第一光信号在与提供第二光信号的第二AWG输出间隔开的第一AWG输出端提供。 即使第二光信号具有与第一光信号相同（或基本相同）的波长，第二光信号也通过第二输出提供。 因此，可以提供单个AWG来复用第一和第二光信号，从而简化PIC设计。

    摘要： A high capacity optical transmitter implemented on a photonic integrated circuit chip comprises a single light source which supplies a continuous wave having a particular wavelength to a plurality of modulators to form modulated optical information signals. A phase shifter is coupled to at least one of the modulators and is used to shift the phase of the corresponding modulated optical information signal associated with a particular modulator. A polarization beam combiner receives each of the modulated optical information signals from the modulators and the modulated optical information signal from the phase shifter and combines each of these signals to form a polarization multiplexed differential quadrature phase-shift keying signal. The light source, the plurality of modulators, the phase shifter and the polarization beam combiner are all integrated on the chip.
