Surface plasmon polariton based photonic integrated devices

Abstract

This paper reports the research on surface plasmon polariton (SPP) based photonic integrated devices. We realized SPP waveguides with very low transmission loss of 0.67dB/mm. By developing a kind of hybrid coupler structure consisted by a SPP waveguide and a dielectric waveguide, a high performance TM/TE polarization splitter was realized with pure TM mode output, and an integrated sensor was demonstrated with rather high sensitivity and the ability for ultra-thin layer sensing.
