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 ...
