| 英文摘要 | An MxN optical star coupler is disclosed which utilizes fiber amplifier technology to provide amplification of message signals. The input signals to the star comprise at least one message signal (S) and at least one pump signal (P₁ -PM-1). The message signals and pump signals combine in an amplifier coupling region (16) to form as an output the amplified message signals (A₁-AN). The amplified message signals are then coupled into the plurality of N output waveguides (18₁-18N). In one embodiment, a plurality of fiber amplifiers are coupled in a one-to-one relationship to the plurality of output waveguides. Since the amplifier is reciprocal in nature, the star may be utilized as a bidirectional device. The couplers may also be connected together to form a cascaded arrangement capable of providing re-amplification of the message signals. |
