Latest Patents
Wang holds a patent for a "Self-tuning optical waveguide filter." This invention is designed to attenuate a lower power light signal at wavelength .lambda..sub.1 more than a higher power signal at wavelength .lambda..sub.2. The filter comprises a length of single-core waveguide and a light injector that applies both wavelengths into the waveguide in two propagating modes subject to mode beating. The mode beating creates high-intensity regions of .lambda..sub.1 that are physically displaced from high-intensity regions of .lambda..sub.2. A portion of the waveguide is doped with a saturable absorber, which disproportionately attenuates wavelengths at lower power levels. The waveguide is preferably a single-core fiber with its central core doped with a rare-earth saturable absorber, specifically Erbium. This design allows for effective propagation of .lambda..sub.1 and .lambda..sub.2 in the LP.sub.01 and LP.sub.02 modes.
