Abstract:
A SOI bent taper structure is used as a mode convertor. By tuning the widths of the bent taper and the bend angles, almost lossless mode conversion is realized between TE0 and TE1 in a silicon waveguide. The simulated loss is <0.05 dB across C-band. This bent taper can be combined with bi-layer TM0-TE1 rotator to reach very high efficient TM0-TE0 polarization rotator. An ultra-compact (9 μm) bi-layer TM0-TE1 taper based on particle swarm optimization is demonstrated. The entire TM0-TE0 rotator has a loss <0.25 dB and polarization extinction ratio >25 dB, worst-case across the C-band.

Claim (Index 24):
The waveguide mode converter of  claim 23  wherein at least one of the curvature or the width of the first bent waveguide segment is configured so that light that enters the first end in the fundamental mode is coupled into a second bent waveguide segment of the bent waveguide taper at least in part in the higher order mode.
