Electrically Poled Vapor-Deposited Organic Glasses for Integrated Electro-Optics
Lauren Dallachiesa, Ivan Biaggio
We introduce electrically-poled small molecule assemblies that can serve as the active electro-optic material in nano-scale guided-wave circuits such as those of the silicon photon…
Dual-Core Optical Fibers for Efficient Mid-Infrared Generation via Third Order Frequency Mixing and Coupling-Length Phase Matching
Jing Su, Ivan Biaggio
Appropriately designed dual-core fibers using coupling-length phase matching (CLPM) allow for phase-matched frequency downconversion over wide frequency intervals using the third-o…
The appeal of small molecules for practical nonlinear optics
Ivan Biaggio
Small organic molecules with a Ï-conjugated system that consists of only a few double or triple bonds can have significantly smaller optical excitation energies when equipped with…
Geminate Exciton Fusion Fluorescence as a Probe of Triplet Exciton Transport after Singlet Fission
Eric A. Wolf, Ivan Biaggio
The geminate annihilation of two triplet excitons created by singlet exciton fission is affected by the dimensionality of transport as determined by typically anisotropic triplet e…
Quantum Beats of a Multiexciton State in Rubrene Single Crystals
Eric A. Wolf, Drew M. Finton, Vincent Zoutenbier +1
We observe quantum beats in the nanosecond-scale photoluminescence decay of rubrene single crystals after photoexcitation with short laser pulses in a magnetic field of 0.1 to 0.3…
