Computational Study of Photonic Crystals Nano-Ring Resonator for Biochemical Sensing

Abstract

Abstract-We investigated the characteristics of photonic crystals (PCs) nano-ring resonators as biochemical sensors theoretically. The new nano-ring resonators were formed by removing holes of a hexagon from a two-dimensional (2-D) silicon PC slab in hexagonal lattice. Resonant peak with quality factor of about 3000 is reported. Biomolecules, e.g., DNAs, trapped in a hole functionalized with molecule probes made the wavelength shift of resonant peak derived in the output terminal. The sensitivity of various sensing holes along the nano-ring was characterized. This new PC nano-ring resonator demonstrated promising features as a biochemical sensor.

Photonic-crystal membranes for optical detection of single nano-particles, designed for biosensor application

“…Some of the most sensitive biosensors with optical readout today are based on dielectric photonic crystals (PCs) [16][17][18][19][20][21] and nanoplasmonics [22][23][24][25][26][27][28]. They all rely on surface chemistry to capture specific target molecules.…”

2d Photonic Crystal Based Biosensor Using Rhombic Ring Resonator for Glucose Monitoring

“…Also higher order of sensing parameters can be achieved by this rhombic ring resonator such as resonant wavelength is in the range of 1540-1560nm, quality factor is of 178.6, 100% of transmission efficiency and sensitivity is of 1000nm/RIU. Hence the higher orders of sensing parameters are achieved in this paper which is greater than literatures reported before [14,22,[15][16][17][18][19][20][21]. The rest of the paper is organized as follows, the proposed design is explained in section 2, simulation results and discussions are reported in section 3 and section 4 concludes the paper.…”

“…Then, the output resonant wavelength is shifted based on their refractive index change. In this they have achieved the quality factor as 3000 whereas sensitivity is about only 6nm/RIU [14]. In 2011, Pal et al have designed PC with nano cavity coupled waveguides where the biosensing possibility is investigated by detecting human IgG molecules to achieve better sensitivity is of 64.5nm/RIU [15].…”

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.)…”
