Latest Patents
Chris Stook holds a patent for "Automatic bias stabilization of dual-polarization in-phase and quadrature optical modulator." This invention includes a method and apparatus for automatic bias stabilization of a dual-polarization IQ modulator based on Mach-Zehnder modulators (MZMs). The technology is designed for transmitting dual-polarization quadrature phase shift keying (DP-QPSK) optical data and DP-16QAM optical data. The apparatus utilizes a unique approach by simultaneously dithering DC-bias voltages of in-phase child, quadrature-phase child, and parent MZMs with three different dither patterns. These patterns are mutually orthogonal in the frequency domain for X and Y polarization IQ modulators. The invention employs tap monitor photodiodes to detect interference terms between the dither patterns, which are then sampled using an ADC in the time domain. This method can solve a set of three simultaneous linear partial differential equations to compute controlled DC-bias voltages, ensuring optimal performance in dual-polarization IQ modulation.
