Latest Patents

Kimura holds a patent for a semiconductor laser module, optical fiber amplifier, and optical transfer. The patent describes an active layer of a semiconductor laser element that is strategically positioned closer to the bottom than to the center of the height of the semiconductor laser element. This design allows a laser beam emitted from the active layer to pass through a collective lens and an optical isolator before entering the incidence portion of an optical fiber. The returning light, reflected by the incidence portion, passes through the optical isolator and the collective lens, ultimately being collected onto the end face of the laser mount. The optical isolator features first and second rutiles that transmit normal light with refraction and abnormal light without refraction, a Faraday element that rotates the polarization plane of transmitted light by 45 degrees, and a permanent magnet that applies a magnetic field to the Faraday element. This innovative approach enhances the efficiency and reliability of optical communication systems.
