Classification: CPC G  H | IPC G  H

Claim 0:
1. A synchronous, tunable multi-optical filter system comprising:
a first tunable optical filter;
one or more second tunable optical filters disposed at one or more predetermined locations proximal to the first tunable optical filter;
a shared diffraction grating disposed in optical paths of both the first tunable optical filter and the one or more second tunable optical filters, wherein the shared diffraction grating is configured to receive collimated beams from input elements of the first tunable optical filter and the one or more second tunable optical filters, and wherein the shared diffraction grating is configured to disperse each of the collimated beams into constituent wavelengths; and
a shared rotatable optical component disposed at a predetermined distance from the shared diffraction grating, wherein the shared rotatable optical component is configured to receive the dispersed each of the collimated beams and communicate output beams having target wavelengths selected from among the constituent wavelengths, to output elements of the first tunable optical filter and the one or more second tunable optical filters operating in individually configurable communication modes; and
wherein each of the one or more second tunable optical filters is tuned synchronously with the first tunable optical filter across a common tuning range by using the shared diffraction grating and by rotating the shared rotatable optical component such that a center wavelength of the first tunable optical filter substantially matches with a center wavelength of the each of the one or more second tunable optical filters.
