Design of nanoslotted photonic crystal waveguide cavities for single nanoparticle trapping and detection
We design and numerically simulate a photonic crystal waveguide cavity with a nanoslot structure for single nanoparticle trapping. A 135x enhancement of optical gradient trapping force compared to plain waveguide trapping devices has been achieved. ©2009 Optical Society of America OCIS codes: (350.4855) Optical tweezers or optical manipulation; (350.4238) Nanophotonics and photonic crystals
متن کاملDetecting Single Gold Nanoparticles (1.8 nm) with Ultrahigh‐Q Air- Mode Photonic Crystal Nanobeam Cavities
The growing applications of nanoparticles in energy and healthcare demand new metrology techniques with improved sensitivity, lower sample concentration, and affordable instrument cost. Here we demonstrate the first air-mode photonic crystal nanobeam cavity with ultrahigh Qfactor (Q = 2.5 × 10) and ultrasmall mode volume (V = 0.01λ) at telecom wavelength. The air-mode cavity has strong field lo...

متن کاملDesign of dispersive optomechanical coupling and cooling in ultrahigh-Q/V slot-type photonic crystal cavities.
We describe the strong optomechanical dynamical interactions in ultrahigh-Q/V slot-type photonic crystal cavities. The dispersive coupling is based on mode-gap photonic crystal cavities with light localization in an air mode with 0.02(λ/n)3 modal volumes while preserving optical cavity Q up to 5×10(6). The mechanical mode is modeled to have fundamental resonance Ωm/2π of 460 MHz and a quality f...
متن کاملMultiplexed Simultaneous High Sensitivity Sensors with High-Order Mode Based on the Integration of Photonic Crystal 1 × 3 Beam Splitter and Three Different Single-Slot PCNCs
We simulated an efficient method for the sensor array of high-sensitivity single-slot photonic crystal nanobeam cavities (PCNCs) on a silicon platform. With the combination of a well-designed photonic crystal waveguide (PhCW) filter and an elaborate single-slot PCNC, a specific high-order resonant mode was filtered for sensing. A 1 × 3 beam splitter carefully established was implemented to spli...
