Latest Patents

Among his latest inventions, Guoliang Li has developed a polarization-independent optical circulator, which is formed in silicon photonics. This circulator employs an optical splitter that includes two couplers connected by two waveguides, one of which is thinner than the other to achieve a substantial effective index difference between TE and TM modes. The inclusion of polarization rotators, whether reciprocal or non-reciprocal, further enhances the functionality of this optical circulator.

Another notable invention is an optical bandpass filter based on reflective devices. This innovative filter comprises an optical splitter with at least four ports, and it utilizes first and second reflectors to couple light effectively. The splitter directs portions of the input light into third and fourth ports, allowing wavelength-selected light to be reflected back toward the splitter while transmitting unwanted wavelengths away, thus optimizing optical performance.
