Journal ArticleDOI
Photonic-crystal GaN light-emitting diodes with tailored guided modes distribution
Aurelien David,Tetsuo Fujii,Rajat Sharma,Kelly McGroddy,Shuji Nakamura,Steven P. DenBaars,Evelyn Hu,Claude Weisbuch,Henri Benisty +8 more
TL;DR: In this article, epitaxial structures which modify the distribution of guided modes were introduced to enhance the potential for efficient light extraction by photonic crystal assisted gallium nitride light-emitting diodes.
Journal ArticleDOI
Directional emission control and increased light extraction in GaN photonic crystal light emitting diodes
Kelly McGroddy,Aurelien David,Elison Matioli,Michael Iza,Shuji Nakamura,Steven P. DenBaars,James S. Speck,Claude Weisbuch,Evelyn L. Hu +8 more
TL;DR: In this paper, a two-dimensional photonic crystal (PhC) light emitting diodes (LEDs) design using both in-plane and index guiding layers (IGLs) in the vertical direction is proposed.
Journal ArticleDOI
Optical and structural properties of GaN nanopillar and nanostripe arrays with embedded InGaN∕GaN multi-quantum wells
Sarah L. Keller,C. Schaake,N. Fichtenbaum,Carl J. Neufeld,Yuan Wu,Kelly McGroddy,Aurelien David,Steven P. DenBaars,Claude Weisbuch,James S. Speck,Umesh Mishra +10 more
TL;DR: In this article, the X-ray reciprocal space maps recorded around the asymmetric reflection revealed that the MQWs in both nanopillars and nanostripes relaxed after nanopatterning and adopted a larger in-plane lattice constant than the underlying GaN layer.
Journal ArticleDOI
Visible resonant modes in GaN-based photonic crystal membrane cavities
Cedrik Meier,K. Hennessy,Elaine D. Haberer,Rajat Sharma,Yong-Seok Choi,Kelly McGroddy,Stacia Keller,Steven P. DenBaars,Shuji Nakamura,Evelyn Hu +9 more
TL;DR: In this article, the first fabrication of fully undercut GaN photonic crystal membranes containing an InGaN multiquantum well layer, fabricated using band-gap-selective photoelectrochemical etching, was presented.
Journal ArticleDOI
GaN/InGaN light emitting diodes with embedded photonic crystal obtained by lateral epitaxial overgrowth
Aurelien David,Brendan Jude Moran,Kelly McGroddy,Elison Matioli,Evelyn L. Hu,Steven P. DenBaars,Shuji Nakamura,Claude Weisbuch +7 more
TL;DR: In this article, a dielectric photonic crystal embedded in the epitaxial layer by lateral epitaxia overgrowth on a patterned GaN template is introduced, which strongly modifies the distribution of guided modes.
