Abstract
The specification describes an optical modulator implemented with an MSK format. The modulator creates two separate pulse streams (one pulse stream comprising the odd bits and the other comprising the even bits of the data stream) using a 1-by-2 pulse generator. The modulator then uses electrooptic phase modulators to encode the odd and even numbered bits separately, and a 50/50 coupler to remix them.
