Ultralow Propagation Loss Slot-Waveguide in High Absorption Active Material
IEEE Photonics Journal, 2014 A slot waveguide formed by high absorption active material is proposed to reduce the propagation loss for monolithic integration. The low propagation loss is attained by concentrating the optical field inside the low-index slot region without absorption.

Mode converter between channel waveguide and slot waveguide
2012 Photonics Global Conference (PGC), 2012 Silicon slot waveguide based mode converter was designed for the effective mode conversion and polarization rotation between a horizontal channel waveguide and a vertical slot waveguide. The device with minimum length of 40µm was demonstrated in amorphous silicon waveguides to provide the mode conversion between the TE mode in the horizontal channel ...
