摘要：

The authors experimentally demonstrate a slot photonic crystal structure for guiding light in a sub-100-nm-wide low-index region. A multimode interference-based coupling structure is introduced to couple light into such a narrow slot photonic crystal waveguide. A coupler of 1.26 mu m long enhances the coupling efficiency by 20 dB for the quasi-transverse-electric mode over 35 nm optical bandwidth centered at 1562 nm. The measured transmission spectra are in good agreement with the simulated band diagram. (c) 2007 American Institute of Physics.
