Abstract: We propose and experimentally demonstrate a broadband, polarization-diverse compact bending design for low-index-contrast waveguides, where light is re-directed via total internal reflection (TIR) on an air-trench quadratic (elliptical or parabolic) reflector surface. Compared to prior… read more here.
