ABSTRACT:
A fiber optical Y-junction device includes a l.times.N optical fiber coupler connected to N fiber optic amplifier module structures constructed from a doped optical fiber. When the optical Y-junction structure contains a fiber optic amplifier, the fiber optical Y-junction device is operable as either a modulator or lossless power divider. A nonblocking optical switch is constructed by coupling M.times.l optical fiber couplers to the outputs of the fiber optic amplifier module structures utilizing the fiber optical Y-junction.
