Abstract
A low-loss polarization-independent and wavelength-insensitive mode converter is demonstrated for coupling between standard single-mode fiber (SMF) and 1.5-¿m-thick silicon waveguides. This mode converter consists of a double-stage taper fabricated using planar processing. Optical testing results show facet loss of approximately -1.5 dB/facet, for TE and TM polarizations across a wide wavelength range.This publication has 13 references indexed in Scilit:
