Abstract
An apparatus for selectively transmitting input optical signals carried on input optical fibers to output optical fibers. A three refractive index tapered wave guide structure is bent and maintained in the bent state. This structure is, thereafter, rotated in the bent state. The coupling characteristics are tunable based on the degree of rotation.
