Nano-slot Waveguides

Nano-slot-waveguide produces high E-field amplitude, optical power, and optical intensity in low-index materials at levels that cannot be achieved with conventional waveguides. This property allows highly efficient interaction between fields and active materials, which may lead to all-optical switching, optical amplification and optical detection on integrated photonics. The work focuses on highly-sensitive nano-slot-waveguide resonator using high index Si3N4 on SiO2 substrate.
