    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： Consistent with the present disclosure, both arms of an MZ interferometer are “double-folded” and are bent in at least two locations to define first and second acute inner angles. Accordingly, the arms of the MZ interferometer may have substantially the same length, and, further, the MZ interferometer has a more compact geometry. In one example, the arms parallel each other and have a serpentine shape, and, in a further embodiment, the arms parallel one another and have a Z-shape. Accordingly, since the temperature of a PIC upon which the MZ interferometer is provided does not vary significantly over such short distances, the temperatures of both arms is substantially the same.

    摘要翻译： 与本公开一致，MZ干涉仪的两个臂是“双折叠”的，并且在至少两个位置弯曲以限定第一和第二锐角内角。 因此，MZ干涉仪的臂可以具有基本上相同的长度，此外，MZ干涉仪具有更紧凑的几何形状。 在一个示例中，臂彼此平行并具有蛇形形状，并且在另一实施例中，臂彼此平行并具有Z形。 因此，由于提供MZ干涉仪的PIC的温度在这么短的距离上没有显着变化，所以两个臂的温度基本相同。

    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.
