The temperature sensitivity of GaAs-based 1.5 /spl mu/m GaInNAsSb lasers
TL;DR: In this paper, the temperature behavior of 1.5 mum GaInNAsSb edge-emitting lasers is analyzed through variation of cavity length and temperature, and it is shown that monomolecular recombination and intervalence band absorption dominate the threshold current, and carrier leakage becomes important at elevated temperatures.
Journal ArticleDOI
Hybrid achromatic microlenses with high numerical apertures and focusing efficiencies across the visible
Corey A. Richards,Christian R. Ocier,Dajie Xie,Haibo Gao,Taylor Robertson,Lynford L. Goddard,Rasmus E. Christiansen,David G. Cahill,Paul V. Braun +8 more
TL;DR: In this paper , using subsurface 3D printing inside mesoporous hosts, the authors densely integrate aligned refractive and diffractive elements, forming thin high performance hybrid achromatic imaging micro-optics.
Proceedings Article
GaInNAsSb/GaNAs VCSELs at 1.46 /spl mu/m
TL;DR: In this article, the authors presented electrically pumped GaInNAsSb VCSELs at 1.46 mum, the longest wavelength on GaAs to date, pulsed at 0.1% duty cycle, with a threshold current density was 4.5 kA/cm2.
Proceedings ArticleDOI
Characterizing microdroplet evaporation using diffraction phase microscopy
Chris Edwards,Amir Arbabi,Basanta Bhaduri,Raman Ganti,Peter Yunker,Arjun G. Yodh,Gabriel Popescu,Lynford L. Goddard +7 more
TL;DR: In this article, a non-destructive in-situ characterization tool with nanometer height resolution that can measure 3D topography is applied to characterize microdroplets during evaporation without any a priori assumptions about the droplet geometry.
