Optical serializer for use in data processing system, has modulation unit receiving unmodulated optical signals, and delay block and optical coupler combining delayed modulated optical signals to produce serialized modulated optical signal

摘要

The serializer (22) has a modulation unit (42) for receiving a set of unmodulated optical signals and a set of electric signals and for producing a set of modulated optical signals using the electric signals to modulate the unmodulated optical signals. A delay block (44) and an optical coupler (46) delay each of the modulated optical signals corresponding to delay duration to produce a set of delayed modulated optical signals and combine the delayed modulated optical signals to produce a serialized modulated optical signal. Independent claims are also included for the following: (1) an optical deserializer including a demodulation unit (2) a data processing system comprising transceiver circuits and an optical communication channel (3) a method for serializing a set of parallel electric signals (4) a method for converting a serialized modulated optical signal into a set of parallel signals.
