Enhancement of bulk second-harmonic generation from silicon nitride films by material composition
K. Koskinen, R. Czaplicki, A. Slablab +8
We present a comprehensive tensorial characterization of second-harmonic generation from silicon nitride films with varying composition. The samples were fabricated using plasma-en…
Atomic layer deposited second order nonlinear optical metamaterial for back-end integration with CMOS-compatible nanophotonic circuitry
StÉphane Clemmen, Artur Hermans, Eduardo Solano +6
We report the fabrication of artificial unidimensional crystals exhibiting an effective bulk second-order nonlinearity. The crystals are created by cycling atomic layer deposition…
Density Functional Theory of Multicomponent Quantum Dots
K. Karkkainen M. Koskinen, S. M. Reimann, M. Manninen
Quantum dots with conduction electrons or holes originating from several bands are considered. We assume the particles are confined in a harmonic potential and assume the electrons…
