Abstract:
An integrated optic device for selecting a desired optical wavelength, comprising:a substrate;a micro-machined surface on said substrate, said micro-machined surface including a reflective surface portion; for receiving broadband optical signals including said desired optical wavelength and having ana tunable filter formed on said substrate, sad tunable filter having an input output, said tunable filter being responsive to control signals to selectively filter said broadband optical signals to provide optical output signals at said desired optical wavelength, said tunable filter comprising a first tunable filter stage and a second tunable filter stage, said first and said second tunable filter stages being coupled in cascade and to said reflective surface portion; andan optical wavelength sensor formed on said substrate, said sensor coupled to said tunable filter to receive said optical output signals and responsive to said optical output signals to produce wavelength indicative signals that are indicative of the wavelength of said optical output signals.
