Handmer C, Martijn de Sterke C, McPhedran R, Botten L, Steel M, Rahmani A
Opt Lett
. 2010 Sep;
35(17):2846-8.
PMID: 20808344
We develop a way to enhance the amplitudes of the nonpropagating evanescent orders of resonant dielectric gratings. We use this blazing to design gratings with spectra tailored to generate steerable...

Wilson I, Botten L
Appl Opt
. 2010 Feb;
16(8):2086-9.
PMID: 20168878
We describe a technique for determining the groove depth of gratings having sinusoidal grooves. Absolute efficiencies measured using a laser are compared with numerical results to give an indication of...

Mahmoodian S, Poulton C, Dossou K, McPhedran R, Botten L, de Sterke C
Opt Express
. 2009 Dec;
17(22):19629-43.
PMID: 19997183
We investigate the formation of photonic crystal waveguide (PCW) modes within the framework of perturbation theory. We derive a differential equation governing the envelope of PCW modes constructed from weak...

Opt Express
. 2009 Nov;
17(20):17338-43.
PMID: 19907519
We show that efficient coupling between fast and slow photonic crystal waveguide modes is possible, provided that there exist strong evanescent modes to match the waveguide fields across the interface....

Opt Express
. 2009 Jun;
15(10):6314-23.
PMID: 19546935
Discrete systems of infinitely long polarizable line dipoles are considered in the quasistatic limit, interacting with a two-dimensional cloaking system consisting of a hollow plasmonic cylindrical shell. A numerical procedure...

Opt Express
. 2009 Jun;
15(8):4753-62.
PMID: 19532721
We consider defect modes created in complete gaps of 2D photonic crystals by perturbing the dielectric constant in some region. We study their evolution from a band edge with increasing...

Opt Express
. 2009 Jun;
14(1):387-96.
PMID: 19503352
We analyze the supermodes in multiple coupled photonic crystal waveguides for long-wavelengths. In the tight-binding limit we obtain analytic results that agree with fully numerical calculations. We find that when...

. 2009 Apr;
26(4):938-48.
PMID: 19340269
Slanted lamellar gratings made of dielectric materials are considered, used in conical diffraction mounts. We extend the modal method for slanted lamellar gratings from classical to conical incidence, develop fully...

. 2008 Nov;
33(22):2644-6.
PMID: 19015695
We consider the coupling into a slow mode that appears near an inflection point in the band structure of a photonic crystal waveguide. Remarkably, the coupling into this slow mode,...
