Efficient broadband second-harmonic generation in a multi-pass cell
Arthur Schönberg, Nikolas Rupp, Ana Oliveira e Silva +6
Second-harmonic generation (SHG) is a widely used nonlinear optical process that has been optimized for high frequency conversion efficiency, broad bandwidths, and optimum spatial…

A systematic design approach for one-dimensional and crossed photonic nanobeam cavities for quantum dot integration
Oscar Camacho Ibarra, Jan-Gabriel Hartel, Atzin David Ruiz Perez +2
We present a systematic workflow for the design of one-dimensional photonic crystal nanobeam cavities with non-zero cavity lengths. By simultaneously optimizing the lattice periodi…
