Abstract:

The present invention provides an optoelectronic device, a method of manufacture therefor and an optical communications system including the same. In an exemplary embodiment, the optoelectronic device includes a wavelength locking device that comprises a low reflector and optical filter. The optical filter an optical filter is located between the low reflector and an input end of the wavelength locking device. The optical filter and low reflector cooperate to lock an oscillation wavelength of a radiation source to a wavelength substantially determined by the optical filter.
