Title: Wavelength-locked external cavity lasers with an integrated modulator

Abstract: An optical transmitter providing the benefits of both filter-locked and wavelength-locked lasers is disclosed by modifying an external cavity (32) for the integration of an optical modulator (14). The external cavity (32) provides a round-trip path for light travel. A substrate (24) is connected to the external cavity (32) where at least one gain element (16) and the optical modulator (14) are integral with the substrate (24). A partial reflector (40) is also integral with the substrate (24) and couples the at least one gain element (16) with the optical modulator (14).
