Title: Hiroshi Komazawa: Innovator in Optical Amplifier Technology
Introduction
Hiroshi Komazawa is a notable inventor based in Isehara, Japan. He has made significant contributions to the field of optical technology, particularly in the development of optical amplifiers. With a total of 3 patents to his name, Komazawa's work has advanced the understanding and functionality of optical systems.
Latest Patents
One of Komazawa's latest patents is an optical amplifier evaluating method and apparatus. This innovative system combines a pulse method using optical modulators with a probe method to accurately measure the gain (G) and noise figure (NF) of optical fiber amplifiers. The system employs a first optical modulator to control the signal light output from a light source, while an optical multiplexer combines this signal with probe light from a second source. A controller manages optical path switches, allowing an optical spectrum analyzer to measure various light intensities, which are then used to calculate the gain and noise figure of the amplifier. This method enhances the precision of optical amplifier evaluations.
Another significant invention by Komazawa is an optical switch capable of detecting switching operations. This device utilizes a stepping motor to ensure accurate coupling between optical fiber collimators. By detecting the direction of the optical axis through a slit disk and corresponding sensors, the system can identify any switching errors, thereby improving the reliability of optical path switching.
