Photonic Crystal Nanocavities for Biosensing Applications
نویسنده
چکیده
In this study, we have investigated photonic crystal (PhC) nanocavities for biosensing applications. The device architecture consists of a PhC waveguide with a defect line for guiding the transmission of light. Resonant nanocavities are coupled to the PhC waveguide by changing the radius of a hole adjacent to the defect line. The devices are fabricated on silicon-on-insulator (SOI) wafers. Preliminary results demonstrate successful detection of human IgG molecules. The PhC waveguide devices are advantageous for medical diagnostics and biosecurity applications as they allow rapid, label-free, and sensitive detection of multiple analytes in a single platform.

Manipulation of Photons by Photonic Crystals
Photonic crystals, in which the refractive index changes periodically, provide an exciting tool for the manipulation of photons and have made substantial progresses in recent years. In this presentation, I will discuss recent progresses in photonic-crystal researches including (i) two-dimensional photonic-crystal cavities and waveguides, (ii) three-dimensional photonic crystals, and (iii) two-d...
متن کاملStrong Optomechanical Interaction in Hybrid Plasmonic-Photonic Crystal Nanocavities with Surface Acoustic Waves
We propose dynamic modulation of a hybrid plasmonic-photonic crystal nanocavity using monochromatic coherent acoustic phonons formed by ultrahigh-frequency surface acoustic waves (SAWs) to achieve strong optomechanical interaction. The crystal nanocavity used in this study consisted of a defective photonic crystal beam coupled to a metal surface with a nanoscale air gap in between and provided ...
متن کاملStimulated Raman amplification and lasing in silicon photonic band gap nanocavities
The concept and design of L5 photonic band gap nanocavities in two-dimensional (2D) photonic crystal (PhCs) slabs for enhancement of timulated Raman amplification and lasing in monolithic silicon is suggested for the first time. Specific high quality factor (Q) and small modal olume nanocavities are designed which supports the required pump–Stokes modal spacing in silicon, with ultra-low lasing...
