Paper Abstract

We experimentally demonstrate a novel slot photonic crystal waveguide for guiding light with low group velocity in a 100-nm-wide low-index region. The unique optical property and structural features of the slotted photonic crystals best match the requirements for active material-based silicon devices. We integrate the novel photonic crystal waveguide with a multimode interference-based coupling structure and measure a 20dB efficiency enhancement compared with direct coupling configuration. The measured transmission spectra are in good agreement with simulated band diagram.
