Nanocavities in Photonic Crystal Waveguides for Label-Free Biosensing

Not Accessible

Your library or personal account may give you access

Abstract

We have investigated resonant nanocavities coupled to photonic crystal waveguides for biosensing. The devices are fabricated using electron beam lithography and reactive-ion-etching. Preliminary results demonstrate successful detection of human IgG molecules and refractive index sensing.
