Computational Characterization of a Photonic Crystal Cantilever Sensor Using a Hexagonal Dual-Nanoring-Based Channel Drop Filter

Abstract

We investigated photonic crystal-based dualnanoring (DNR) channel drop filters for nanomechanical sensor applications. The backward drop mechanism is explained by a proposed model. A resonant peak at 1553.6 nm with a quality factor better than 3800 is observed at the backward drop port. When this DNR is integrated at the junction between the silicon cantilever and the substrate, the deformation of the silicon cantilever can be detected in terms of the resonant wavelength and resonant wavelength shift. The derived minimum detectable force is 37 nN.

Two-dimensional photonic crystal based sensor for pressure sensing

“…Based on above sensing mechanisms, the optical sensors have been designed and analyzed, using directional couplers [5], Mach-Zehnder interferometers [6], nano-ring resonators [4,[7][8][9][10][11][12], and micro-ring resonators [13,14] for different applications, reported in the literature. In the literature, PC/PCRR (photonic crystal ring resonator) based sensors were reported for chemical sensing, force and strain sensing [7][8][9][10][11][12], refractive index and gas sensing [15][16][17], dengue virus detection [18], pressure sensing [12,19,20], aqueous environment [21] and biosensing (proteins, avidins, BSA, DNA, etc.)…”

Lateral lattice shift engineered slow light in elliptical photonics crystal waveguides

“…The ultraconfinement of light in a PhC nanocavity structure in the subwavelength scale, typically in ðλ∕nÞ 3 orders, enables the existence of very high quality factor optical localized resonances. 1 Such high confinement of energy in a small volume enables a variety of scientific and engineering applications, such as high-sensitivity sensors, 2-5 ultracompact filters, [6][7][8][9] fast modulators, 10 low-power all-optical switches, 11 and tunable optical resonators. 12,13 By extending the cavity defect in the PhC to a line defect of missing air holes, a PhC waveguide is created and works in the slow-light regime.…”

Photonic Crystal-Based force Sensor to Measure Sub-Micro Newton forces over a Wide Range

“…A sensitivity of 0.1 nm/76 nN with an average quality factor (Q) of 3470 is obtained. Li et al 17,18 presented a more sensitive device which consists of a dual PhC ring resonator on a 220 nm thick silicon cantilever. Among different configurations of sensors that are reported in these contributions, the most sensitive device has a minimum detectable force as 7.58 nN, but with a drastically reduced Q of 876.…”
