Titel
Integration of polarisation independent mode transformers with uncladded InGaAsP/InP rib waveguides
Abstract
Polarisation independent mode transformers were fabricated by core thickness tapering in uncladded InGaAsP/InP rib waveguides intended for integration into PICs. No epitaxial regrowth is needed. The coupling loss for flat-end fibres is reduced to (2.3+or-0.2) dB at alignment tolerances of >+or-2.4 mu m for 1 dB excess loss.
