Latest Patents

Tanaka's latest patents include an innovative method for manufacturing optical fiber gratings. This method involves intermittently heating an optical fiber that has a core with residual stress in the longitudinal direction. By softening the peripheral cladding of the core, spatial periodical changes in the relative refractive index between the core and cladding are formed. This process allows for the index of refraction of the core to change through the release of the residual stress. The result is an optical fiber grating that does not require expensive equipment, exhibits high productivity, and maintains stable grating characteristics over time.
