Abstract
We propose a waveguide integrated plasmonic platform in order to deliver excitation power to and collect signal efficiently from a nanoantenna. The system consists of a silicon waveguide with an integrated nanoantenna and a fiber spot size converter. The nanoantenna is designed to have a broad resonance around 1.5 microns with an estimated surface enhanced Raman scattering (SERS) enhancement of 6 orders of magnitude and collection efficiency up to 80%. The device is fabricated on a silicon-on-insulator (SOI) wafer. The proposed and fabricated device can be used in applications such as on-chip SERS spectroscopy, infrared spectroscopy and gas sensing.
