Austin G. Griffith,Ryan K. W. Lau,Jaime Cardenas,Yoshitomo Okawachi,Aseema Mohanty,Romy Fain,Yoon Ho Daniel Lee,Mengjie Yu,Christopher T. Phare,Carl B. Poitras,Alexander L. Gaeta,Michal Lipson +11 more
TL;DR: It is reported that the first on-chip integrated mid-infrared frequency comb using a silicon optical parametric oscillator ring resonator is reported, and a 750-nm-wide comb centered at 2.6 um is demonstrated.
Journal ArticleDOI
Large-scale optical phased array using a low-power multi-pass silicon photonic platform
Steven A. Miller,You-Chia Chang,Christopher T. Phare,Min Chul Shin,Moshe Zadka,Samantha P. Roberts,Brian Stern,Xingchen Ji,Aseema Mohanty,Oscar A. Jimenez Gordillo,Utsav D. Dave,Michal Lipson +11 more
TL;DR: In this paper, a multi-pass photonic platform is integrated into a large-scale phased array that reduces phase shifter power consumption by nearly 9 times, without sacrificing speed or optical bandwidth.
Journal ArticleDOI
Singlet Exciton Fission in Nanostructured Organic Solar Cells
TL;DR: Organic solar cells comprised of tetracene, copper phthalocyanine, and the buckyball C(60) are reported, demonstrating that exciton fission can efficiently compete with exciton dissociation on the nanoscale.
Journal ArticleDOI
Triplet Exciton Dissociation in Singlet Exciton Fission Photovoltaics
Priya Jadhav,Patrick O. Brown,Nicholas J. Thompson,Benjamin H. Wunsch,Aseema Mohanty,Shane R. Yost,Eric Hontz,Troy Van Voorhis,Moungi G. Bawendi,Vladimir Bulovic,Marc A. Baldo +10 more
TL;DR: Using photocurrent spectroscopy and a magnetic field probe it is found that colloidal PbSe nanocrystals are the most promising acceptors, capable of efficient triplet exciton dissociation and long wavelength absorption.
Journal ArticleDOI
Reconfigurable nanophotonic silicon probes for sub-millisecond deep-brain optical stimulation.
