Abstract:
1. A device comprising: a first waveguide configured to operate in a first mode, wherein the first waveguide is configured to receive a first wave and propagate the first wave in the first mode along a first path; and a second waveguide in optical communication with the first waveguide, the second waveguide configured to operate in a second mode and a third mode, wherein the second waveguide includes a reflection surface, wherein the reflecting surface is configured to generate scattering of light and an inter-modal conversion of waves, wherein the first waveguide is a single mode fiber and the second waveguide is a photonic crystal fiber, wherein the single mode fiber is coupled to the photonic crystal fiber at a fusion location, wherein the photonic crystal fiber comprises walls defining a plurality of holes, and wherein the second waveguide is configured to: propagate the fourth reflected wave in the second mode in the second path.
