PINCH WAVEGUIDE

摘要

A waveguide is provided including a first photon propagating material having a first index of refraction (n1) and having a pinch disposed therein, the pinch having a second index of refraction (nl1); and a second photon propagating material disposed in optical communication with the first photon propagating material and having a third index of refraction (n2); wherein n1'< n1, n1'<n2, and the pinch redirects at least a portion of the photons from the first photon propagating material to the second photon propagating material.
