Abstract:
An optical switch comprising:an optical input configured to provide a plurality of optical channels, the optical input optically coupled to a passive wavelength-selective optical component disposed to optically couple at least one selected optical channel of the plurality of optical channels to an active Fabry-Perot structure configured to transmit the at least one selected optical channel to a first optical output when the Fabry-Perot structure is in a transmissive state and to reflect the at least one selected optical channel to a second optical output when the Fabry-Perot structure is in a reflective state, the optical switch switching between the first state and the second state in response to a control signal, and the passive wavelength-selective optical component disposed to optically couple a remainder of the plurality of optical channels to the second optical output.
