Photonic crystal all-polymer slab resonators

Journal of Applied Physics, 2005
Moderate air-hole-fraction photonic crystal square lattice structures defining small cavity resonators were created by etching air holes of 0.15μm radius to a depth of 3μm in an all-polymer slab waveguide. Transmission measurements with subnanometer resolution resolved the complete transmission spectra and highly resonant defect peaks with quality ...

Suspended photonic crystal slabs for biosensing

SPIE Proceedings, 2010
Label-free optical biosensors based on photonic crystal slabs offer high sensitivity and simplified coupling to incoming free-space radiation. Biosensing results from detecting shifts in guided resonance frequency spectral location based on changes in index of refraction due to analytes binding at the PC slab surface. We have evaluated biosensing for

Guided modes in photonic crystal slabs

Physical Review B, 1999
We analyze the properties of two-dimensionally periodic dielectric structures that have a band gap for propagation in a plane and that use index guiding to confine light in the third dimension. Such structures are more amenable to fabrication than photonic crystals with full three-dimensional band gaps, but retain or approximate many of the latter's ...

Single layer silicon photonic crystal slab

Photonics and Nanostructures - Fundamentals and Applications, 2012
Abstract We present here the fabrication and characterization of single layer silicon photonic crystal mirror on a silicon-on-insulator wafer. By a combination of electron beam lithography, fast atom beam etching with deep reactive ion etching, silicon photonic crystal slabs are achieved on 260 nm freestanding silicon membrane and sandwiched with air

Coupling into photonic crystal slab waveguides

Postconference Digest Quantum Electronics and Laser Science, 2003. QELS., 2003
An adiabatic taper method is presented for coupling light into photonic crystal defect waveguides in a square lattice of circular dielectric rods. The taper consists of two coupling stages.

Fano resonances of photonic crystal slabs

ACOFT/AOS 2006 - Australian Conference on Optical Fibre Technology/Australian Optical Society, 2006
A Bloch mode theory for diffraction of plane waves by planar PC slabs is developed. The theory provides physical insight into the origin of Fano resonances, allowing a simple pole model to be deduced rigorously.

Linear waveguides in photonic-crystal slabs

Physical Review B, 2000
Linear waveguides in photonic-crystal slabs, two-dimensionally periodic dielectric structures of finite height, are fundamentally different from waveguides in two-dimensional photonic crystals. The most important distinctions arise from the fact that photonic-crystal slab waveguides must be index-confined in the vertical direction ~while a band gap ...

Photonic crystal slab quantum cascade detector

Applied Physics Letters, 2013
In this Letter, we demonstrate the design, fabrication, and characterization of a photonic crystal slab quantum cascade detector (PCS-QCD). By employing a specifically designed resonant cavity, the performance of the photodetector is improved in three distinct ways. The PCS makes the QCD sensitive to surface normal incident light.

Photonic crystal slab with layered elements

SPIE Proceedings, 2011
Abstract We introduce the simulation of a photonic crystal slab with a square lattice, whose basis elements are layered cylinders of an averaged refractive index . We compare it with a similar photonic crystal with a basis of the same size and a refractive index matching to the average of the layered ones.
