Problems solved by technology
[0011] The major drawbacks of existing wavelength calibration methods and apparatus relate in part to laser design and techniques enabling the calibration process as well as automation and software control of the calibration
These alignment drawbacks limit the market for tunable lasers, as well as optical subassemblies and communication modules employing them, by adding cost, time, and complexity to manufacturing, as well as limitations on recalibration when installed in a product or deployed in the field

A method and apparatus for calibrating and controlling tunable lasers are disclosed. Multiple methodologies disclosed herein may be used, alone or in combination, which significantly speed up a calibration time and thus provide a significant advantage over existing technology in calibrating the tunable lasers. Certain methodologies benefit from a unique design of the tunable lasers that couple two or more optical facets to an output. The tunable lasers may be equipped with two or more sampled grating distributed Bragg reflector (SGDBR) mirrors and may include Semiconductor Optical Amplifiers (SOAs) after the SGDBR mirrors.
Description
technical field [0001] This patent application claims U.S. Serial No. 62 / 073,713, entitled "Method and Apparatus for Rapid Calibration and Programming of Tunable Lasers and Associated Transmitters and Optical Subassemblies," filed October 31, 2014 The benefit of the Provisional Patent Application, the entire disclosure of which is hereby incorporated by reference in its entirety. Background technique [0002] Today's fiber-optic-based networks use transceivers as interfaces between electronics and optical signals propagating on optical fibers and at other points in the network, where information is converted between electronic and optical forms. [0003] An optical communication device comprising photonic and / or optoelectronic devices and components for transmitting, encoding, receiving, decoding optical data for transmission over an optical fiber is interfaced to control these elements and on the transmitting and receiving sides Various electronic circuits that interface d...
