On observation of dispersion in tunable second-order nonlinearities of silicon-rich nitride thin films
Hung-Hsi Lin, Rajat Sharma, Alex Friedman +5
We present experimental results on second-harmonic generation in non-stoichiometric, silicon-rich nitride (SRN) films. The as-deposited film presents a second-order nonlinear coeff…
Integrated and Steerable Vortex Lasers using Bound States in Continuum
B. Bahari, F. Vallini, T. Lepetit +5
Orbital angular momentum is a fundamental degree of freedom of light that manifests itself even at the single photon level. The coherent generation and beaming of structured light…
Characterizing the effects of free carriers in fully-etched, dielectric-clad silicon waveguides
Rajat Sharma, Matthew W. Puckett, Hung-Hsi Lin +2
We theoretically characterize the free-carrier plasma dispersion effect in fully-etched silicon waveguides, with various dielectric material claddings, due to fixed and interface c…
Induced Optical Losses in Optoelectronic Devices due to Focused Ion Beam Damages
Felipe Vallini, Luís Alberto Mijan Barea, Elohim Fonseca dos Reis +2
A study of damages caused by gallium focused ion beam (FIB) into III-V compounds is presented. Potential damages caused by local heating, ion implantation, and selective sputtering…
