Waveguide-integrated colour centres in silicon carbide with broadband photonic crystal reflectors for efficient readout
Marcel Krumrein, Julian M. Bopp, Timo Steidl +5
Spin-active colour centres in 4H silicon carbide are promising candidates as building blocks for quantum information applications. To increase the photon count rate of the emitters…

Precise characterization of a silicon carbide waveguide fiber interface
Marcel Krumrein, Raphael Nold, Flavie Davidson-Marquis +13
Emitters in high refractive index materials like 4H-SiC suffer from reduced detection of photons because of losses caused by total internal reflection. Thus, integration into effic…
