Summary:Embodiments of a method and apparatus for tunable wavelength conversion using a Bragg grating and a gain medium disposed in a semiconductor substrate are disclosed herein. In one embodiment, an input optical signal corresponding to a first wavelength and modulated with a data component may be directed into the gain medium (e.g., a quantum cascade intersubband laser) to cause emission of light of at least one wavelength distinct from the first wavelength and modulated with the data component of the input optical signal. At least a portion of the emitted light may then be reflected from the tunable Bragg grating to cause stimulated emission of the selected Bragg wavelength, thereby generating an output optical signal corresponding to a wavelength distinct from the first wavelength, and modulated with the data component of the input optical signal.
