ABSTRACT:
According to an exemplary embodiment of the present invention, an optical apparatus includes an optical filter array which comprises a plurality of optical filter elements, wherein at least one of the optical filter elements is adapted for tuning to two or more wavelengths.According to another exemplary embodiment of the present invention, an optical apparatus includes a monolithic optical filter array which further includes at least one tunable optical filter element. The optical apparatus also includes a tuning mechanism which tunes the tunable optical filter element to extract a signal of a particular wavelength from an optical signal which includes a plurality of wavelengths.According to another exemplary embodiment of the present invention, a method for selectively extracting optical signals of particular wavelengths includes providing a monolithic optical filter array which further includes at least one tunable optical filter element. The method also includes tuning the tunable optical filter element to extract a signal of a particular wavelength from an optical signal which includes a plurality of wavelengths.
