Claim Text:
1. A monolithically integrated optical transmitter comprising: at least one substrate; a tunable laser resonator monolithically integrated with the substrate, the laser resonator configured to output radiation along an optical axis; a first modulator monolithically integrated with the substrate, the first modulator including a first input waveguide configured to receive a first portion of the radiation output from the tunable laser resonator and modulate at least one of intensity or phase of the first portion of the radiation output from the tunable laser resonator; a second modulator monolithically integrated with the substrate, the second modulator including a second input waveguide configured to receive a second portion of the radiation output from the tunable laser resonator and modulate at least one of intensity or phase of the second portion of the radiation output from the tunable laser resonator; and an optical redirector integrated with the first or second input waveguide, the optical redirector configured to change the direction of propagation of optical radiation in the waveguide it is integrated with.
