Journal ArticleDOI
Using end groups to tune the linear and nonlinear optical properties of bis(dioxaborine)-terminated polymethine dyes.
Jonathan D. Matichak,Joel M. Hales,Shino Ohira,Stephen Barlow,Sei-Hum Jang,Alex K.-Y. Jen,Jean-Luc Brédas,Joseph W. Perry,Seth R. Marder +8 more
TL;DR: Six anionic pentamethine dyes with different 2,2-difluoro-4-aryl-1,3,2(2 H)-dioxaborin-6-yl termini were synthesized and isolated as tetra-n-octylammonium salts with a variety of aryl groups appended to increase conjugation beyond the dioxaborine termini to result in an overall increase in Re(gamma).
Journal ArticleDOI
Electro-optic (E-O) molecular glasses.
Sei-Hum Jang,Alex K.-Y. Jen +1 more
TL;DR: This Focus Review describes molecular glasses as a new class of materials for nonlinear optical (NLO) applications, especially for electro-optic (E-O) devices, and introduces promising architectures to prepare morphologically stable molecular glasses with large E-O activities and improved material properties for device applications.
Journal ArticleDOI
Reducing cross-sensitivity of TiO2-(B) nanowires to humidity using ultraviolet illumination for trace explosive detection
TL;DR: This finding proves that the reduction of cross-sensitivity to humidity through UV irradiation is an effective approach that can improve the performance of a sensor based on TiO2-(B) nanowires for the detection of explosive gas.
Journal ArticleDOI
Phosphonic acid self-assembled monolayer and amorphous hafnium oxide hybrid dielectric for high performance polymer thin film transistors on plastic substrates
Orb Acton,Itaru Osaka,Guy Ting,Daniel O. Hutchins,Hong Ma,Richard D. McCullough,Alex K.-Y. Jen +6 more
TL;DR: In this paper, a vacuum-free solution processed hybrid dielectric composed of an n-octadecyl-phosphonic acid self-assembled monolayer on amorphous sol-gel processed hafnium oxide (HfOx) is demonstrated for lowvoltage polymer semiconductor-based thin film transistors (TFTs).
Journal ArticleDOI
A silicon-organic hybrid platform for quantum microwave-to-optical transduction
Jeremy D. Witmer,Timothy P. McKenna,Patricio Arrangoiz-Arriola,Raphaël Van Laer,Raphaël Van Laer,E. Alex Wollack,Francis Lin,Alex K.-Y. Jen,Jingdong Luo,Amir H. Safavi-Naeini +9 more
TL;DR: In this article, the authors present a platform for electro-optic photon conversion based on silicon-organic hybrid photonics, which combines high quality factor microwave and optical resonators with an electrooptic polymer cladding to perform microwave-to-optical photon conversion from 6.7 GHz to 193 THz.
