Latest Patents

One of his latest patents is titled "Discretely ITU-T channel grid wavelength tunable single longitudinal mode erbium-doped fiber ring laser." This invention provides a fiber ring laser capable of obtaining a back-up laser light and standard light with a wavelength continuously tuned in a single mode. The laser operates with equal spacing of 12.5 GHz, 25 GHz, 50 GHz, or 100 GHz, as recommended by ITU-T Recommendations G. 692 & G. 694.1 in both C-band and L-band. The design incorporates a fiber tunable etalon filter, an air gap etalon filter, and a saturable absorber within an optical fiber laser resonator. This innovative fiber ring laser can generate laser light with a wavelength tuned by more than 70 nm, excellent output power flatness, and a source spontaneous emission ratio exceeding 70 dB across 361 channels with equal spacing of 25 GHz.

Another notable patent is the "Method for correcting the shift of output wavelength of light source." This invention offers a method for correcting the shift of an output wavelength by deriving simple equations through experimental processes. It predicts the degree of output wavelength shift concerning varied input currents and adjusts the drive temperature accordingly. This method is advantageous as it allows for locking the output wavelength of each light source without the need for continuous operation of a wavelength locker or measuring device, thereby reducing the operating costs of optical communication systems.
