Latest Patents
Ryu Izawa 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 from a 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 decreases as it moves away from the center. The design allows for some of the transmitting light to leak into the clad at the radially expanded core part. This leakage minimizes the travel of light through the clad to the output end of the optical fiber, effectively providing the function of an optical attenuator. The attenuation can be precisely adjusted by controlling the size of the radially expanded core part. Additionally, the design prevents the reflection of transmitting light back to the input side, minimizing reflectance.
