Enhanced light emission from gap plasmons in nano-strip MIM tunnel junctions
Saurabh Kishen, Jinal Tapar, Naresh Kumar Emani
Electrical excitation of light using inelastic electron tunneling is a promising approach for the realization of ultra-compact on-chip optical sources with high modulation bandwidt…
Enhancement of the optical gain in GaAs nanocylinders for nanophotonic applications
Jinal K. Tapar, Saurabh Kishen, Kumar Prashant +2
Semiconductor nanolasers based on micro disks, photonic crystal cavities, and metallo-dielectric nanocavities have been studied during the last decade for on-chip light source appl…
Lasing action in active dielectric nanoantenna arrays
Son Tung Ha, Yuan Hsing Fu, Naresh Kumar Emani +4
Directional lasing, with a low threshold and high quality factor, in active dielectric nanoantenna arrays is demonstrated. This is achieved through a leaky resonance excited in cou…
Plasmonic resonances in nanostructured transparent conducting oxide films
Jongbum Kim, Gururaj V. Naik, Naresh K. Emani +1
Transparent conducting oxides (TCO) are emerging as possible alternative constituent materials to replace noble metals such as silver and gold for low-loss plasmonic and metamateri…
