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 ...

Single layer silicon photonic crystal slab
Photonics and Nanostructures - Fundamentals and Applications, 2012Abstract 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., 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.

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.

Photonic crystal slab quantum cascade detector
Applied Physics Letters, 2013In 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, 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.

Tunable one-dimensional photonic crystal slabs
SPIE Proceedings, 2007A 1D photonic crystal slab based on preferential etching of commercially available silicon-on-insulator wafers is presented. Compared to dry etching, anisotropic wet etching is more tolerant to errors as it is self-stopping on crystallographic {111} planes and it produces a more precise geometry with symmetries and homothetic properties, with surface ...
