Latest Patents

Himura holds a patent for an optical attenuator and a method of making the same. This invention involves exposing one or more parts of an optical fiber to a high temperature gas flame for approximately 30 minutes. This process forms radially expanded core parts, where the diameter of the core is increased at the center and then moderately decreased as it moves away from the center. The design allows for some of the transmitting light to leak into the clad at the expanded core part, effectively functioning as an optical attenuator. The attenuation can be precisely adjusted by controlling the size of the radially expanded core part. Additionally, the invention minimizes reflectance by preventing the reflecting back of transmitting light to the input side.
