Role of Edge Inclination in an Optical Microdisk Resonator for Label-Free Sensing

Article, Other literature type English OPEN
Gandolf, Davide; Ramiro Manzano, Fernando; Aparicio Rebollo, Francisco Javier; Pucker, Georg; Pavesi, Lorenzo;

In this paper, we report on the measurement and modeling of enhanced optical refractometric sensors based on whispering gallery modes. The devices under test are optical microresonators made of silicon nitride on silicon oxide, which differ in their sidewall inclination... View more
