Nonvolatile Plasmonics Based on Optically Reprogrammable Phase Change Materials

Here, a new platform for realization of novel nonvolatile optical switching devices was proposed that takes an advantage high field confinement provided by plasmonics and multi-state programming capabilities chalcogenide phase change materials. A reduction in the overall energy consumption consists enhancement plasmonic allow to lower energies implementation materials operate under zero-static power consumption. combination provide additionally essential improvement terms time, attenuation contrast possibility perform shift with wide bandgap In most all-optical photonic devices, mechanism is realized optically through heating two stage process based on absorption light itself, heat transfer from metal stripe metal. Thus, compared any other previously presented switches, even show zero can be implemented structure. The waveguide arrangement extremely sensitive changes material properties, thus, minor temperature provides transmitted light.
