LIGHT SIGNAL PROCESSING DEVICE AND LIGHT SIGNAL STORING DEVICE |
摘要 |
There is provided a light signal processing device. The light signal processing device includes a label recognition circuit and an electro-absorption optical switch. The label recognition circuit includes: a plurality of photodiodes coupled to each other in parallel; a resonant tunneling diode coupled in series with the photodiodes; and a data buffer coupled to a connection point between the photodiodes and the resonant tunneling diode. The label recognition circuit is adapted to latch an optical bit signal inputted into the photodiodes. The electro-absorption optical switch is driven directly by an output signal outputted from the label recognition circuit.
