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： High speed optical modulators can be made of k modulators connected in series disposed on one of a variety of semiconductor substrates. An electrical signal propagating in a microwave transmission line is tapped off of the transmission line at regular intervals and is amplified by k distributed amplifiers. Each of the outputs of the k distributed amplifiers is connected to a respective one of the k modulators. Distributed amplifier modulators can have much higher modulating speeds than a comparable lumped element modulator, due to the lower capacitance of each of the k modulators. Distributed amplifier modulators can have much higher modulating speeds than a comparable traveling wave modulator, due to the impedance matching provided by the distributed amplifiers.

摘要： The gain-bandwidth (GBW) limitation problem inherent in all amplifiers is overcome to provide wideband amplifiers with specified characteristics for the transfer function. Parasitic capacitances of transistors are absorbed or incorporated into the design of the passive networks, which are inserted between the gain stages of the amplifier. The component values are determined based on conventional low-pass filter structures. A prototype CMOS transimpedance amplifier implemented using the developed technique achieves over 9 GHz bandwidth and 54 dB transimpedance gain from a 0.5 pF photo-diode capacitance.
