Fabrication of Flexible Photonic Crystal Slabs

MRS Proceedings, 2014
ABSTRACTTwo methods for the fabrication of flexible and stretchable photonic crystal slabs are demonstrated and compared. In both cases a periodically nanostructured polydimethylsiloxane (PDMS) membrane is used as substrate. The first method is based on oblique-angle vapor deposition of SiO as a high refractive index material onto the nanostructured ...

Two-Dimensional Photonic Crystal Slabs

2004
In this chapter we treat PC slabs such that the thickness is on the order of the wavelength of light. In this case we cannot treat the problem in terms of only plane waves with k parallel to the slab plane, so the situation is quite different from the 2D PC case. Essentially we need to treat the case in a 3D way, but in a way different also from the 3D

Terahertz Tag Using Photonic-Crystal Slabs

Journal of Lightwave Technology, 2018
To realize the concept of the Internet of Everything (IoE), which has attracted significant interest, information tags directly attached to objects constitute one of the key technologies. However, in terms of security and uniqueness, the current information tags are unsatisfactory.

Optical computing using photonic crystal slabs

Photonic and Phononic Properties of Engineered Nanostructures IX, 2019
We discuss the use of photonic crystal slab to accomplish a number of imaging processing tasks, including edge detection, image smoothing, white noise suppression and, suppression or extraction of periodic features. All these tasks involve filtering in the wavevector domain. Image filtering can be implemented electronically.

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.
