Journal ArticleDOI
P-type interface charge control layers for enabling GaN/SiC separate absorption and multiplication avalanche photodiodes
Anand V. Sampath,Qiugui Zhou,Ryan Enck,Dion McIntosh,Hongen Shen,J. C. Campbell,Michael Wraback +6 more
TL;DR: In this article, a p-type interface charge control layer (PICCL) is introduced that enables optimization of the net positive polarization induced interface charge at the GaN/SiC interface.
Journal ArticleDOI
Excitonic recombination of degenerate two-dimensional electrons with localized photoexcited holes in a single heterojunction quantum well.
P. A. Folkes,Mitra Dutta,S. Rudin,Hongen Shen,Weimin Zhou,Doran D. Smith,M. Taysing-Lara,Peter G. Newman,Melanie W. Cole +8 more
TL;DR: In this article, the excitonic recombination of degenerate quasi-two-dimensional (Q2D) electrons with localized photoexcited holes has been observed in low-temperature photoluminescence and magnetophotonicity spectra.
Journal ArticleDOI
A 2 x 2 crosspoint switch fabricated on the passive active resonant coupler (PARC) platform
TL;DR: In this article, the authors demonstrate the fabrication of a 2/spl times 2 crosspoint switch monolithically fabricated on the passive active resonant coupler (PARC) platform by utilizing vertical resonant coupling over a taper between an active and a passive waveguide.
Proceedings ArticleDOI
Characterization of InGaAs self-mixing detectors for chirp amplitude-modulated ladar (CAML)
Keith Aliberti,William C. Ruff,Hongen Shen,Peter G. Newman,Mark M. Giza,Wendy L. Sarney,Michael R. Stead,John F. Dammann,R. Mehandru,Fan Ren +9 more
TL;DR: The U.S. Army Research Laboratory has developed a number of near-infrared, prototype laser detection and ranging (LADAR) Systems based on the chirp, amplitude-modulated LADAR (CAML) architecture as mentioned in this paper.
Journal ArticleDOI
Intensity dependent time‐resolved photoluminescence studies of GaN/AlGaN multiple quantum wells of varying well width on laterally overgrown a‐plane and planar c‐plane GaN
Gregory A. Garrett,Hongen Shen,Michael Wraback,Bilge Imer,Benjamin A. Haskell,James S. Speck,Sarah L. Keller,Shuji Nakamura,Steven P. DenBaars +8 more
TL;DR: In this paper, the authors investigated the effect of pump intensity on photoluminescence (PL) downconversion and time-correlated single photon counting in GaN/AIGaN multiple quantum wells.
