We report on the fabrication and characterization of high-Q microtoroid resonators made of low-loss modified polymers by the two-photon stereolithography process. We found that polymer resonators can be fabricated in a high-speed process, and measure

We demonstrate label-free optical biosensing using a horizontal air-slotted silicon-rich silicon nitride (SiNx) microdisk resonator. Due to the strong confinement of light in the air-slot, a large resonance shift of 6.2 nm is observed upon reaction o
