Abstract
A waveguide taper design for uncladded rib or channel waveguides on In GaAsP-InP with polarization-independent coupling loss to the fiber is proposed. The spot size variation of the guided mode along the taper i s investigated numerically by a two-dimensional finite dfference metho d. By introducing thin guiding layers below the waveguide it is shown that the taper structure can be designed to have relaxed fabrication t olerances and a mode matching loss to the fiber of 1dB.
