TL;DR: In this article, a new EO polymer, AJ309, which undergoes thermal cross-linking during the poling process was used for hybrid sol-gel EO modulators, achieving 0.65V VπMach-Zehnder modulators.
Journal ArticleDOI
Corrections to “A Silicon-Polymer Hybrid Modulator—Design, Simulation, and Proof of Principle” [Dec 13 4067-4072]
Roland Himmelhuber,Oscar D. Herrera,Ram Voorakaranam,Li Li,Adam Jones,Robert A. Norwood,Jingdong Luo,Alex K.-Y. Jen,Nasser Peyghambarian +8 more
TL;DR: In this article, an error was found in the code used for calculating the line capacitance of a CPS electrode design, and corrections are presented here. But the error is not addressed in this paper.
Proceedings ArticleDOI
Plasmon-Enhanced Third-Order Harmonic Generation in Plasmonic-Organic Photonic Crystals
TL;DR: In this paper, the authors presented theoretical and experimental analysis of extraordinary third-order harmonic generation (THG) by organic materials on a plasmonic photonic crystal and showed that the hybrid nanostructure platform provided over 20 times enhancement in THG efficiency.
Proceedings ArticleDOI
Transparent Conducting Oxide (TCO) Electrode Based High-speed Organic Electro-optic (EO) Modulator
Shuai Wu,Fei Yi,Boyang Liu,Yingyan Huang,Seng-Tiong Ho,Yiliang Wang,Jun Liu,Hu Kang,Tobin J. Marks,Jingdong Luo,Neil M. Tucker,Alex K.-Y. Jen +11 more
TL;DR: A novel organic Mach Zehnder EO modulator using TCO as electrodes has been demonstrated in this article, which is suitable for high frequency operation by engineering TCO material conductivity and loss.
Proceedings ArticleDOI
Organic/Inorganic Hybrid Sol-Gels as Cladding Materials for Electro-Optic Polymer Based Devices
Christopher T. DeRose,Robert A. Norwood,Mahmoud Fallahi,Nasser Peyghambarian,Alex K.-Y. Jen,Jingdong Luo +5 more
TL;DR: The electro-optic coefficient of AJl8 chromophore doped in APC was enhanced by more than a factor of 2 by using a 5 micron organic/inorganic hybrid sol-gel cladding layer as discussed by the authors.
