Latest Patents

One of his latest patents is an optical pulse tester. This device includes an optical divider that causes return light to divide into first and second divided light. It features a first optical receiver that receives the first divided light and outputs a first optical receiver signal, along with a second optical receiver for the second divided light. The signal processor in this invention obtains a waveform indicating the intensity distribution of the return light in the longitudinal direction of the optical fiber. This is achieved by performing level conversion of the signals based on the divided ratio of the optical divider and the sensitivities of the optical receivers.

Another significant patent is a light source device that incorporates a semiconductor laser. This device has a first end surface and a second end surface that form a first resonator. An optical system is positioned on the optical path of the laser light emitted from the semiconductor laser, forming a second resonator. The optical system has a reflection characteristic that ensures higher reflectance for light within a specified wavelength range compared to the first end surface.
