Claim 7:
8. The synchronous, tunable multi-optical filter system of claim 1, further comprising an optical assembly disposed between the shared diffraction grating and the input elements of the first tunable optical filter and the one or more second tunable optical filters for reducing bandwidths of the first tunable optical filter and the one or more second tunable optical filters, wherein the optical assembly is configured to adjust size of the collimated beams incident on the shared diffraction grating such that the bandwidths of the first tunable optical filter and the one or more second tunable optical filters are different, while the center wavelength and tuning range of the first tunable optical filter are common to the center wavelength and tuning range of the each of the one or more second tunable optical filters respectively.
