Journal ArticleDOI
The use of sodium salts as nucleation agents for polyethylene terephthalate with minimal molecular weight reduction
TL;DR: In this paper, several sodium carboxylates have been found based on pyrrole carboxylic acid that are effective as nucleants but which do not cause a reduction in the molecular weight of PET.
Journal ArticleDOI
A Triptycene-Containing Chromophore for Improved Temporal Stability of Highly Efficient Guest−Host Electrooptic Polymers
Brent M. Polishak,Su Huang,Jingdong Luo,Zhengwei Shi,Xing-Hua Zhou,Albert Hsu,Alex K.-Y. Jen +6 more
Journal ArticleDOI
Photobleaching Fabrication of Microring Resonator in a Chromophore-Containing Polymer
TL;DR: In this paper, photobleaching is used for the fabrication of polymer waveguide microring resonators for the first time, which can be used to make polymer thin films that are not compatible with other fabrication techniques, and therefore can be a useful complement to traditional fabrication methods.
Journal ArticleDOI
Zwitterionic Cyanine–Cyanine Salt: Structure and Optical Properties
Zhong'an Li,Peng Zhao,Salimeh Tofighi,Rajesh Sharma,Trenton R. Ensley,Sei-Hum Jang,David J. Hagan,Eric W. Van Stryland,Alex K.-Y. Jen +8 more
TL;DR: In this paper, a covalently linked complementary cyanine complex of cationic and anionic heptamethines forming a highly polarizable zwitterionic cyanine-cyanine salt was studied in detail on both its electronic structure and optical properties.
Journal ArticleDOI
Transversely tapered hybrid electro-optic polymer/sol-gel Mach–Zehnder waveguide modulators
Yasufumi Enami,D. Mathine,Christopher T. DeRose,Robert A. Norwood,Jingdong Luo,Alex K.-Y. Jen,Nasser Peyghambarian +6 more
TL;DR: In this paper, the authors proposed a hybrid modulator structure that reduces both the optical loss and half wave voltage (Vπ) with a sol-gel waveguide core transversely sandwiched between two Mach-Zehnder arms of EO polymer cores.
