Abstract
Low-loss spot size converters (SSC) are important elements for coupling photonic
integrated circuits to fibres. We have developed a Cl2-based inductively-coupled-plasma
process to etch non-selectively InP and photo-resist (PR). This process was then used to
transfer a vertically-tapered PR pattern into an InP/InGaAsP structure. The tapered PR
pattern was made using a standard optical lithography combined with sliding-mask
technique. One, 2 and 3-mm long SSCs were fabricated and characterized. Excess
losses between 0.5-2 dB were measured for all SSCs. We also fabricated lateral SSCs
using the same epi-structure, however these SSCs showed higher losses (>4dB/SSC).
