Latest Patents

Hang Guan holds a patent for "Reducing back reflection in hybrid lasers." This invention tackles the problem of large back reflection, which can lead to degradation in relative intensity noise (RIN), linewidth broadening, and mode hopping. The patented hybrid laser design includes a mode converter that effectively converts a higher-back-reflection mode of light into a mode that provides less back reflection to the gain chip. The mode converter may consist of a polarization rotator, a waveguide converter, or a high-order mode converter. Additionally, a routing waveguide may be incorporated, featuring a phase shifter, such as a doped waveguide, to adjust the cavity length of the laser cavity.
