ABSTRACT:
A method for optical spectrum analysis provides a tunable optical filter and scans a wavelength range of an optical signal that is larger than the free spectrum range of the tunable optical filter. The optical signal is filtered through the tunable optical filter. Separate multiple optical orders of the wavelengths scanned and filtered by the tunable optical filter are individually detected.
