Abstract
An apparatus for generating a variable wavelength optical signal. The apparatus includes a signal generator for generating an optical signal. A reflector receives a portion of the optical signal and an electrical tuning signal. The reflector is responsive to the optical and tuning signals, reflecting a selected spectral component of the optical signal back to the signal generator. The generator receives the selected spectral component and responds by stabilizing the wavelength of its output at the wavelength of the spectral component.
