Unidirectional frequency conversion in microring resonators for on-chip frequency-multiplexed single-photon sources
Mikkel Heuck, Jacob Gade Koefoed, Jesper Bjerge Christensen +4
Microring resonators are attractive for low-power frequency conversion via Bragg-scattering four-wave-mixing due to their comb-like resonance spectrum. However, conversion efficien…
Benchmarking five numerical simulation techniques for computing resonance wavelengths and quality factors in photonic crystal membrane line defect cavities
Jakob Rosenkrantz de Lasson, Lars Hagedorn Frandsen, Philipp Gutsche +10
We present numerical studies of two photonic crystal membrane microcavities, a short line-defect cavity with relatively low quality () factor and a longer cavity with high .…
Slow-light-enhanced energy efficiency for the graphene microheater on silicon photonic crystal waveguides
Siqi Yan, Xiaolong Zhu, Lars Hagedorn Frandsen +4
Slow light has been widely utilized to obtain enhanced nonlinearities, enhanced spontaneous emissions, and increased phase shifts owing to its ability to promote light-matter inter…
Effective electro-optical modulation with high extinction ratio by a graphene-silicon microring resonator
Yunhong Ding, Xiaolong Zhu, Sanshui Xiao +4
Graphene opens up for novel optoelectronic applications thanks to its high carrier mobility, ultra-large absorption bandwidth, and extremely fast material response. In particular,…
