ABSTRACT:
A stable switched multifrequency source is described. The stable switched multifrequency source includes a narrowband reflective optical filter bank. This bank includes a plurality of narrowband reflective optical filter devices. In one embodiment, the stability and precision of the reflectivity of the narrowband reflective optical filter devices is further enhanced through regulation via temperature and/or bias current based on a comparison of the output wavelength and a precise stable wavelength reference. The stable switched multifrequency source also includes an optical switch that is coupled to each of the narrowband reflective optical filter devices.
