摘要： An integrated control system for a laser and Mach-Zehnder interferometer are disclosed and may include configuring a bias point for low-speed control of an optical modulator utilizing control circuitry integrated on the same CMOS die. The optical modulator may be differentially monitored. A laser source for the modulator may be controlled utilizing monitor photodiodes via optical taps on outputs of the modulator, or utilizing a monitor photodiode on one output port of the modulator, which may comprise a Mach-Zehnder interferometer. An error signal may be generated by subtracting monitor photodiode signals from optical taps on output ports of the modulator. The bias point of the modulator may be adjusted by minimizing the error signal. Calibration time of the bias point may be reduced utilizing electronic data inversion. An output of the modulator may comprise a Y-junction and a single monitor photodiode may measure both branches of the modulator.

摘要： A method and system for integrated power combiners are disclosed and may include a chip comprising a polarization controller, the polarization controller comprising an input optical waveguide, optical couplers, and a polarization-splitting grating coupler. The chip may be operable to: generate two output signals from a first optical coupler that receives an input signal from said input optical waveguide, phase modulate one or both of the two output signals to configure a phase offset between the two generated output signals before communicating signals with the phase offset to a second optical coupler. One or both optical signals generated by said second optical coupler may be phase modulated to configure a phase offset between signals communicated to the polarization-splitting grating coupler; and an optical signal of a desired polarization may be launched into an optical fiber via the polarization-splitting grating coupler by combining the signals communicated to the polarization-splitting grating coupler.

摘要： A system for integrated power combiners is disclosed and may include receiving optical signals in input optical waveguides and phase-modulating the signals to configure a phase offset between signals received at a first optical coupler, where the first optical coupler may generate output signals having substantially equal optical powers. Output signals of the first optical coupler may be phase-modulated to configure a phase offset between signals received at a second optical coupler, which may generate an output signal having an optical power of essentially zero and a second output signal having a maximized optical power. Optical signals received by the input optical waveguides may be generated utilizing a polarization-splitting grating coupler to enable polarization-insensitive combining of optical signals. Optical power may be monitored using optical detectors. The monitoring of optical power may be used to determine a desired phase offset between the signals received at the first optical coupler.
