Resonator Arrays for Linear Position Sensors

Design guidelines for optical resonator biochemical sensors

In this paper, we propose a design tool for dielectric optical resonator-based biochemical refractometry sensors. Analagous to the widely accepted photodetector figure-of-merit, the detectivity D*, we introduce a new sensor system figure of merit, the time-normalized sensitivity S*, to enable quantitative, cross-technology-platform comparison between resonator sensors with distinctive device de...

Slowing light with Fabry–Perot resonator arrays

We analyze the transmission of light through coupled-resonator optical waveguides in the form of evanescently coupled Fabry–Perot resonator arrays. We develop a transfer matrix method to calculate the amplitude and phase responses of the arrays. We also discuss the inclusion of optical gain in the system to compensate for losses in these structures. Owing to the compact length along the propaga...

Critical coupling in plasmonic resonator arrays.

We report critical coupling of electromagnetic waves to plasmonic cavity arrays fabricated on Moiré surfaces. Dark field plasmon microscopy imaging and polarization dependent spectroscopic reflection measurements reveal the critical coupling conditions of the cavities. The critical coupling conditions depend on the superperiod of the Moiré surface, which also defines the coupling between the ca...

Plasma generation by dielectric resonator arrays

Arrays of dielectric resonators—illuminated by an antenna—are used to ignite and sustain multiple microwave plasmas in parallel. Calcium titanate cylindrical resonators were arranged in a linear array with separation distances between 0.5 and 5 mm. The operating frequency was near the HEM111 resonance of 1.1 GHz. Paschen curves of the breakdown field and voltage in argon atmosphere are consiste...
