Abstract
A device. The device includes a substrate a substrate, a first optical waveguide disposed on the substrate and a second optical waveguide disposed on the substrate. The device further includes a coupling element disposed on the substrate, the coupling element configured to couple an optical signal in the first optical waveguide to the second optical waveguide, and couple an optical signal in the second optical waveguide to the first optical waveguide. A first reflective element is disposed at an end of the first optical waveguide configured to reflect optical signals in the first optical waveguide. A second reflective element disposed at an end of the second optical waveguide configured to reflect signals in the second optical waveguide.
