Leaky mode expansion for optical fibre sensor application

A multimode interference (MMI) based sensor for high refractive index sensing was proposed and demonstrated in this simulation work. The proposed sensor scheme works by a mode expansion according to leaky modes instead of traditionally used radiation modes. The simulation work tried to exhibit wheth...
