Claim (Index 20):
A distributed traveling wave modulator, comprising:\n an optical input for receiving an input optical signal and splitting the input optical signal into first and second portions; a first plurality of optical phase-shifters connected in series optically coupled to the optical input for receiving the first portion of the input optical signal; a second plurality of optical phase-shifters connected in series optically coupled to the optical input for receiving the second portion of the input optical signal, respective pairs of the first and second plurality of optical phase-shifters forming sequential modulators; an optical output for recombining the first and second portions forming a modulated output optical signal; a differential electrical data input connected to a data source; a plurality of driver amplifier stages, each including a respective differential driver amplifier input, a differential driver amplifier output, and a differential signal output connected to a respective one of the sequential modulators, the differential driver amplifier input of a first of said plurality of driver amplifier stages connected to the differential electrical data input; and a plurality of delay/relay stages, each including a respective differential delay/relay input connected to a differential driver amplifier output of a previous driver amplifier stage, and a differential delay/relay output connected to a differential driver amplifier input of a following driver amplifier stage; wherein an optical delay of each optical phase-shifter plus optical waveguide wiring matches a delay between the driver amplifier stages so that modulations constructively add.
