Abstract
Official abstract text for this publication.
A tunable optical transmitter, comprising a tunable laser comprising a distributed Bragg reflector (DBR) section, a phase section, and a gain section, a photodiode detector (PD) optically coupled to the tunable laser, wherein the tunable optical transmitter lacks a temperature controller, and wherein the tunable optical transmitter is configured to lock onto a wavelength at different operating temperatures.
First claim
Opening claim text (preview).
What is claimed is: 1. A transmitter comprising: a tunable laser comprising: a distributed Bragg reflector (DBR) section comprising a facet, a phase section coupled to the DBR section, and a gain section coupled to the phase section and configured to emit light from the tunable laser; a photodiode (PD) coupled to the facet; and a processor coupled to the PD and configured to: instruct application of a first range of currents to the DBR section, a second current to the…
