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 ...

Polymer photonic crystal slab waveguides
Applied Physics Letters, 2001We present details of the fabrication, calculations, and transmission measurements for finite two-dimensional (2D) polymer photonic crystal (PC) slab waveguides, which were fabricated from a benzocyclobutene polymer on a low refractive index substrate from Teflon. A square air hole lattice (500 nm lattice constant, 300 nm hole diameter) was realized by

Photonic crystal slab with layered elements
SPIE Proceedings, 2011Abstract 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.

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 ...

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.

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.

Controlling light with slab photonic crystal
2011This thesis presents novel designs and schemes for wavelength demultiplexing, frequency conversion and multi-wavelength generation applications, achieved by engineering the band structure and dynamic control of the dispersion in planar photonic crystal (PhC) platform. The composite superprism demultiplexer, whereby simultaneous diffraction compensation
