Abstract
A method of converting an optical wavelength includes providing a wavelength converter assembly with a photodetector and a laser that have a common epitaxial structure with areas of differing bandgap. The laser including a laser resonator. An optical input with a first wavelength is absorbed at the wavelength converter assembly. A first electrical signal is generated from the photodetector in response to the optical input. The first electrical signal is conditioned and produces a conditioned first electrical signal. A second electrical signal is generated from the conditioned first electrical signal. A laser output is generated from a gain medium of the laser at a second wavelength in response to the second electrical signal.
