"HAD (hybridized-active-dielectric) nanowire, using hybrid glassy material... switchable material properties upon illumination of optical pulses... shows selective responses to specific polarization direction... information simultaneously processed using multiple polarizations in different directions... multiple polarization channels, leading to  enhancement in computing density by several orders... computing speeds are faster because these nanowires are modulated by nanosecond optical pulses"
