Abstract

Many structures containing lateral taper waveguide in previous papers showed quite high experimental loss. A vertical tapered waveguide of both rib and nanowire waveguides together with SU8 lateral tapered waveguide for mode size conversion to single mode fibre has been designed. Taper shape profile, offset tolerance have been investigated and get overlapping loss of less than 0.1 dB and 97% coupling efficiency.
