| 摘要 |
Low loss optical couplers for an optical data bus include a first component having permanent input/output connections to the bus and a reference face capable of reflecting energy from the input to the output. If optical energy is to be coupled into or out of the bus, a second component is secured to the first component. The second component has input and/or output optical connections and a reference face which contacts at least part of the reference face of the first component and which permits optical energy to be transferred between the two components. Frequency-selective encoders and decoders using active optical devices are also disclosed. |
