摘要：

Spotsize converters (SSC's), consisting of a lateral taper, thin-film core, and ridge, have been accurately designed to develop spotsize-converted laser diodes (SS-LD's) in the 1.3-mu m-wavelength region based on the 3-D semivectorial finite-difference beam propagation method (FD-BPM) with nonequidistant discretization, The effects of the structural parameters on the sum of spot-conversion loss and coupling loss between the laser diode eigenmode and single-mode fiber (SMF) eigenmode are clarified, It is shown that a small loss of around 1.5 dB can be realized by introducing nonlinear tapers to these types of SSC's, The calculated results agree well with the measured results.
