Polyoxometalates (POMs), a type of giant transition metal oxide clusters on the nanoscale, are emerging as useful materials with unique catalytic, electrooptical, and biological properties. Lanthanide-containing POMs elements show excellent photoluminescent properties with narrow emission bands, large Stokes shift, long lifetime, and tunable emission, i.e., their long emission timescale (microt...

The electric-field induced absorption changes (Stark effect) of reconstituted light-harvesting complex II (LHCII) in different oligomerisation states-monomers and trimers-with different xanthophyll content have been probed at 77 K. The Stark spectra of the reconstituted control samples, containing the xanthophylls lutein and neoxanthin, are very similar to previously reported spectra of native ...

In this paper we study the resource requirements of electrooptical organizations in performing digital computing tasks. We define a generic model of parallel computation using optical interconnects, called the optical model of computation (OMC). In this model, computation is performed in digital electronics and communication is performed using free space optics. Using this model we derive relat...

Photolysis into the longest wavelength absorption band of 2-tert-butyl-2,3-diazabicyclo[2.2.2]oct-3-yl hydrazine (Hy) substituted naphthalenes causes aryl group reduction electron transfer to give (+)Hy-Ar(-). Electrooptical absorption measurements characterize the charge separation properties from these bands. Emission studies demonstrate that the separation between absorption and emission max...

We propose a theoretical analysis of the stochastic dynamics miniature optoelectronic oscillators (OEOs) based on whispering-gallery mode resonators. The core element in this microwave photonic oscillator is high-Q resonator with quadratic nonlinearity, which simultaneously performs electrooptical modulation, frequency filtering and energy storage. This multi-task allows to feature improved siz...
