Abstract:
An optical system can automatically lock an adjustable spectral filter to a first wavelength of an incoming light signal, and can automatically filter an additional incoming light signal at the first wavelength. A tunable filter can have a filtering spectrum with an adjustable peak wavelength and increasing attenuation at wavelengths away from the adjustable peak wavelength. The tunable filter can receive first input light, having a first wavelength, and can spectrally filter the first input light to form first output light. A detector can detect at least a fraction of the first output light. Circuitry coupled to the detector and the tunable filter can tune the tunable filter to maximize a signal from the detector and thereby adjust the peak wavelength to match the first wavelength. The tunable filter further can receive second input light and spectrally filter the second input light at the first wavelength.

Claim (Index 7):
The optical system of  claim 6 , wherein the tunable filter further comprises:\n a material having a temperature-dependent refractive index disposed in an optical path of the optical ring resonator; and a heater configured to controllably heat at least a portion of the material, and thereby change an optical path length around the optical ring resonator and thereby change a resonant wavelength of the optical ring resonator, wherein the first circuitry is further configured to tune the tunable filter by heating the portion of the material.
