Latest Patents

His latest patents include a method and apparatus for bias control with a large dynamic range for Mach-Zehnder modulators. This invention describes improved dither detection, measurement, and voltage bias adjustments for an electro-optical modulator. The electro-optical modulator generally includes RF electrodes and phase heaters interfaced with semiconductor waveguides on the arms of Mach-Zehnder interferometers. A processor is connected to output a bias tuning voltage to the electro-optical modulator for controlling optical modulation. A variable gain amplifier (VGA) can be configured with AC coupling connected to receive a signal from a transimpedance amplifier (TIA) that amplifies a photodetector signal from an optical tap used to measure an optical signal with a dither signal. The analog to digital converter (ADC) can be connected to receive output from the VGA. The processor can receive the signal from the ADC and output the bias tuning voltage based on the evaluation of the signal from the tap.
