ABSTRACT:
An optical coupler 10 has two fibers 20, 30 that are adjacent each other in a coupling region 12. One of the fibers has a clad doped with a photosensitive glass, such as germania. The photosensitive glass is exposed to suitable radiation to alter the index of refraction of fiber and tune the coupler 10 to the selected coupling frequency.
