Optimization of photonic waveguide bends for low index contrast material platforms
Ritu Jangra, Kushagra Agarwal, Posa Harsha Vardhan +2
Compact and low loss waveguide bends are vital for enhancing the integration density of on chip photonic devices. The bend loss becomes extremely critical, particularly for compact…
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…
Second harmonic generation with plasmonic metasurfaces: direct comparison of electric and magnetic resonances
Rohith Chandrasekar, Naresh K. Emani, Alexei Lagutchev +4
Plasmonic resonances in metallic nanostructures have been shown to drastically enhance local electromagnetic fields, and thereby increase the efficiency of nonlinear optical phenom…
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…
Searching for Better Plasmonic Materials
Paul West, Satoshi Ishii, Gururaj Naik +3
Plasmonics is a research area merging the fields of optics and nanoelectronics by confining light with relatively large free-space wavelength to the nanometer scale - thereby enabl…
