摘要： A photonic frequency routing type time division highway switch which requires no conflict control at the input side, and incorporates no inherent splitting loss of the optical signal power. The switch is formed by a plurality of tunable frequency convertors for allocating frequency channels to the optical signals on the input highways at each timeslot; a frequency router for connecting the optical signals outputted from the frequency convertors to its outputs according to the frequency channels allocated to the optical signals at each timeslot; and a plurality of frequency multiplexed output buffers for outputting the optical signals outputted from the frequency router to the output highways such that a plurality of optical signals with different frequency channels which are in an identical timeslot are outputted at different timeslots.

摘要： A photonic frequency division multiplexed FIFO buffer capable of realizing a multiple input one output FIFO buffer or a one input one output FIFO buffer by using only a small number of buffers. This buffer is formed by a plurality of loop shaped optical waveguide delay lines for storing the input optical signals from the time division multiplexed input highway, which are connected in series by a plurality of 2.times.2 optical switches for selectively transferring the input optical signals among the loop shaped optical waveguide delay lines. This buffer also includes a 1.times.2 frequency channel selector, connected at a last stage of the loop shaped optical waveguide delay lines, for selectively outputting optical signals in specific frequency channels among the input optical signals stored by the last stage of the loop shaped optical waveguide delay lines as the output optical signals to the timeslots on the time division multiplexed output highway.
