Uncladded InGaAsP/InP rib waveguides with integrated thickness tapers for efficient fibre-chip butt coupling

Abstract
The thickness of the waveguide core of uncladded InGaAsP/InP rib waveguides is tapered to fabricate new spot-size transformers without epitaxial regrowth or etching of deep grooves. The coupling loss for flat-end fibres is reduced by 7 dB at alignment tolerances of >+or-2.0 mu m for 1 dB excess loss.
