Journal ArticleDOI
Spin coherence and dephasing in GaN
Bernd Beschoten,Ezekiel Johnston-Halperin,D. K. Young,Martino Poggio,J. E. Grimaldi,Sarah L. Keller,Steven P. DenBaars,Umesh K. Mishra,Evelyn L. Hu,David D. Awschalom +9 more
TL;DR: In this article, a time-resolved Faraday rotation is used to measure electron spin coherence in n-type GaN epilayers and the dependence on both magnetic field and temperature is found to be qualitatively similar to previous studies in these systems.
Journal ArticleDOI
Fabrication and Characterization of Two-Dimensional Photonic Crystal Microcavities in Nanocrystalline Diamond
C. F. Wang,Ronald Hanson,Tatyana Feygelson,Jie Yang,James E. Butler,David D. Awschalom,Evelyn L. Hu +6 more
TL;DR: In this article, fabrication and optical characterization of high quality photonic crystal (PC) microcavities based on nanocrystalline diamond was reported. But the results of the characterization were limited to three-dimensional Finite Difference Difference Time Domain (FDTD) simulations.
Journal ArticleDOI
Room-temperature continuous-wave operation of 1.54-μm vertical-cavity lasers
Dubravko Babic,K. Streubel,Richard P. Mirin,N.M. Margalit,John E. Bowers,Evelyn L. Hu,D.E. Mars,Long Yang,K. Carey +8 more
TL;DR: In this article, the authors report on the room-temperature continuous-wave operation of vertical-cavity lasers operating at 1.54 /spl mu/m. The devices use a 7 strain-compensated quantum-well active layer sandwiched between two Al(Ga)As-GaAs quarter-wave mirrors joined by wafer fusion.
Journal ArticleDOI
Fabrication and characterization of two-dimensional photonic crystal microcavities in nanocrystalline diamond
C. F. Wang,Ronald Hanson,David D. Awschalom,Evelyn L. Hu,Tatyana Feygelson,J. Yang,James E. Butler +6 more
TL;DR: In this article, the authors report fabrication and optical characterization of high quality photonic crystal microcavities based on nanocrystalline diamond, which offer exceptional opportunity to study cavity quantum electrodynamics at room temperature.
Journal ArticleDOI
Optical properties of InGaN quantum wells
Shigefusa F. Chichibu,Amber C. Abare,Michael Mack,M. S. Minsky,Takahiro Deguchi,Daniel Cohen,Peter Kozodoy,S. B. Fleischer,Sarah L. Keller,James S. Speck,John E. Bowers,Evelyn L. Hu,Umesh K. Mishra,Larry A. Coldren,Steven P. DenBaars,K. Wada,Takayuki Sota,Shuji Nakamura +17 more
TL;DR: In this paper, the emission mechanisms of strained InGaN quantum wells (QWs) were shown to vary depending on the well thickness L and InN molar fraction x, where Si-doping was found to improve the interface quality and surface morphology, resulting in an efficient carrier transfer from high to low bandgap energy portions of the well.
