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…
