Latest Patents

Zeng holds a patent for a "High-power single-mode triple-ridge waveguide semiconductor laser." This invention proposes a supersymmetry (SUSY)-based triple-ridge waveguide semiconductor laser structure. The design includes an electrically pumped main broad-ridge waveguide located in the middle, flanked by a pair of lossy auxiliary partner waveguides. These auxiliary waveguides are engineered to provide dissipative modes that can phase match and couple with the higher-order modes in the main waveguide. By manipulating the gain-loss discrimination of the modes in the laser cavity, Zeng's design effectively suppresses undesired higher-order transverse modes while maintaining the fundamental mode. This ensures stable single-mode operation with a larger emitting aperture and higher output power compared to conventional single-transverse-mode ridge waveguide diode lasers. Zeng has 1 patent to his name.
