Abstract
A device may include a first optical port configured to receive an optical signal and a demultiplexer to spatially separate the optical signal into multiple optical signals. Each of the multiple optical signal may have a different carrier wavelength. The device may also include a switch element with plasmons. The switch element may receive one of the multiple optical signals, direct the received one of the multiple optical signals, and couple energy of the plasmons to energy of the directed optical signal. The device may further include a second optical port. The second optical port may receive the directed optical signal with the coupled energy of the plasmons, and transmit the received, directed optical signal.
