Latest Patents

Yangjing Wen holds a patent for a "Method and apparatus of automatic bias control for intensity modulated silicon modulator." This patent describes systems and methods that provide automatic bias control for intensity modulated silicon modulators. The invention involves supplying laser light to a Mach-Zehnder modulator (MZM) and splitting the laser light into two arms. In this setup, light in the first arm undergoes a phase section for data modulation, while the second arm receives heat for bias control and also includes a phase section for data modulation. The process includes providing a first output light from the MZM, a complementary output light from a monitor photodetector (mPD), and applying an uneven spacing 3-level square wave as dither for automatic bias control of the MZM, which operates at quad point and phase tuning with a heater. This innovative approach enhances the efficiency and reliability of silicon modulators.
