Double-Slot Optical Ring Resonator Sensor

Double-Slot Hybrid Plasmonic Ring Resonator Used for Optical Sensors and Modulators

An ultra-high sensitivity double-slot hybrid plasmonic (DSHP) ring resonator, used for optical sensors and modulators, is developed. Due to high index contrast, as well as plasmonic enhancement, a considerable part of the optical energy is concentrated in the narrow slots between Si and plasmonic materials (silver is used in this paper), which leads to high sensitivity to the infiltrating mater...

Triangularly phase-modulated optical fiber ring resonator sensor.

An optical fiber ring resonatory sensor system has been demonstrated by applying a triangular phase modulation signal to a fiber loop. The dynamic range for detection of optical phase change is 2pi. The sensor is linear within this range. The minimum detectable optical phase change is 1.5 x10(-4) rad/Hz((1/2)).

A packaged optical slot-waveguide ring resonator sensor array for multiplex label-free assays in labs-on-chips.

We present the design, fabrication, and characterisation of an array of optical slot-waveguide ring resonator sensors, integrated with microfluidic sample handling in a compact cartridge, for multiplexed real-time label-free biosensing. Multiplexing not only enables high throughput, but also provides reference channels for drift compensation and control experiments. Our use of alignment toleran...

Photonic Crystal Ring Resonator Based Optical Filters

Optical fiber ring resonator characterization by optical time-domain reflectometry.

A novel method for characterization of optical fiber resonators by an optical time-domain reflectometry (OTDR) technique is reported. This easy-to-use technique yields accurate results for cavity lengths ranging from a few meters to several kilometers. A simple relationship is established between the round-trip cavity loss and the position where the OTDR signal is maximum. The value obtained fo...
