Journal ArticleDOI
High quality factor photonic crystal nanobeam cavities
TL;DR: In this paper, the authors investigated the design, fabrication, and experimental characterization of high quality factor photonic crystal nanobeam cavities in silicon using a five-hole tapered one-dimensional photonic mirror and precise control of the cavity length.
Journal ArticleDOI
Photonic crystal nanobeam cavity strongly coupled to the feeding waveguide
TL;DR: In this article, a deterministic design of an ultrahigh Q-factor, wavelength-scale photonic crystal nanobeam cavity is proposed and experimentally demonstrated using this approach, cavities with Q>106 and on-resonance transmission T>90% are designed.
Journal ArticleDOI
Diamond nonlinear photonics

TL;DR: In this article, an optical parametric oscillator in the telecom wavelength range is realized in a diamond system consisting of a ring resonator coupled to a diamond waveguide, and threshold powers as low as 20mW are measured and up to 20 new wavelengths are generated from a single-frequency pump laser.
Journal ArticleDOI
Visualization of exciton transport in ordered and disordered molecular solids
Gleb M. Akselrod,Parag B. Deotare,Nicholas J. Thompson,Jiye Lee,William A. Tisdale,Marc A. Baldo,Vinod M. Menon,Vladimir Bulovic +7 more
TL;DR: It is demonstrated that the mechanism of exciton transport depends strongly on the nanoscale morphology, which has wide implications for the design of excitonic materials and devices.
Journal ArticleDOI

TL;DR: Direct nanoscale imaging of the transport of long-lived CT states in molecular organic donor-acceptor blends demonstrates that the bound electron-hole pairs that form the CT states move geminately over distances of 5-10 nm, driven by energetic disorder and diffusion to lower energy sites.
