Fabrication of Flexible Photonic Crystal Slabs
MRS Proceedings, 2014ABSTRACTTwo 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 ...

Suspended photonic crystal slabs for biosensing
SPIE Proceedings, 2010Label-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

Coherent Thermal Antenna Using a Photonic Crystal Slab
Physical Review Letters, 2006We show that a photonic crystal film can emit coherent thermal radiation. We demonstrate the key role of leaky waves existing at the air-photonic crystal interface. The frequency and direction of emission depend on the lattice parameters. This paves the way towards the design of coherent infrared antennas.

Fano resonances of photonic crystal slabs
ACOFT/AOS 2006 - Australian Conference on Optical Fibre Technology/Australian Optical Society, 2006A 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.

Coupling into photonic crystal slab waveguides
Postconference Digest Quantum Electronics and Laser Science, 2003. QELS., 2003An 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.

Photonic crystal slotted slab waveguides
Photonics and Nanostructures - Fundamentals and Applications, 2008We report on the fabrication of photonic crystal waveguides in SOI that comprise an air-slot in the centre. The slot serves to confine suitably polarised optical radiation (H-polarisation) and due to its small size, provides extremely high field intensity values out with the high index material.

Guided modes in photonic crystal slabs
Physical Review B, 1999We 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 ...

Ultrasound Sensing with a Photonic Crystal Slab
Conference on Lasers and Electro-Optics, 2018We experimentally demonstrate a compact architecture for ultrasound acoustic sensing based upon a photonic crystal slab (PCS) fabricated on top of a thin mechanically pliable silicon substrate. A noise-equivalent pressure of 2.0 kPa (0.072 kPa/√Hz) at 5 MHz is observed.
