ABSTRACT:
A fast tunable optical filter with unique selection means, capable of being monolithically integrated on silica or semiconductive wafers, includes a frequency routing device (FRD) for receiving up to P input optical signals and responsively providing up to Q outputs, where P and Q are integers greater than or equal to one, at least one input selecting device for selectively coupling up to P optical signals to the FRD, and at least one output selecting device for selectively inhibiting up to Q outputs of said FRD.
