Claim 12:
13. A method for synchronously tuning wavelengths of output beams in one of an optical system and an optoelectronic system, the method comprising:
disposing a synchronous, tunable multi-optical filter system in the one of the optical system and the optoelectronic system, the 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, wherein the first tunable optical filter and the one or more second tunable optical filters are configured to operate in individual communication modes;
a shared diffraction grating disposed in optical paths of both the first tunable optical filter and the one or more second tunable optical filters; and
a shared rotatable optical component disposed at a predetermined distance from the shared diffraction grating;

receiving, by the shared diffraction grating, collimated beams from input elements of the first tunable optical filter and the one or more second tunable optical filters;
dispersing, by the shared diffraction grating, each of the received collimated beams into constituent wavelengths; and
selecting target wavelengths from among the constituent wavelengths and communicating output beams having the target wavelengths to output elements of the first tunable optical filter and the one or more second tunable optical filters, by rotating the shared rotatable optical component, wherein by using the shared diffraction grating and by rotating the shared rotatable optical component, each of the one or more second tunable optical filters is tuned synchronously with the first tunable optical filter across a common tuning range 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.
