Harnessing of temporal dispersion for integrated pump filtering in spontaneous heralded single-photon generation processes
Julian Brockmeier, Timon Schapeler, Nina Amelie Lange +4
Cointegration of heralded single-photon generation and on-chip detection requires the ability to differentiate between pump light and single photons. We explored the dispersion-ind…
