The detection techniques used in biosensors can be broadly classified into label-based and
label-free. Label-based detection relies on the specific properties of labels for detecting a …

We demonstrate a highly sensitive label-free Mach–Zehnder interferometer (MZI) biosensor
based on silicon nitride slot waveguide. Unlike the conventional MZI sensors, the sensing …

We demonstrate a chip-scale photonic system for the room-temperature detection of gas
composition and pressure using a slotted silicon microring resonator. We measure shifts in …

We report an experimental demonstration of an integrated biochemical sensor based on a
slot-waveguide microring resonator. The microresonator is fabricated on a Si_3N_4-SiO_2 …
