We report our recent efforts for the design and fabrication of comb slot photonic crystal waveguides in silicon on insulator photonics. The main issues related to dispersion engineering, investigation of slow mode optical losses, and modal confinement metrics, have been investigated in various geometries. Nonlinear χ(3) optical properties have then been explored using a pump probe picosecond experiment and the obtained trends and results are discussed.
