Abstract

We report the broadband luminescence enhancement of erbium ions embedded in a non-resonant hybrid waveguide photon-emitter interface on silicon. The measured emission rate enhancement of > 300 is enabled by a large radiative Purcell factor across the spectrum in the telecommunications C-band. This enables the shortening of the lifetime of erbium from 3 ms to 8 μs, effectively providing brighter on-chip photon sources. The platform efficiently collects the photon emission of erbium in a single-mode waveguide and out-couples it to a low-loss photonic waveguide using a reverse nano-focusing method. This hybrid approach opens a large range of possible emitter-waveguide platform combinations for heterogeneous and hybrid quantum emitter integration, towards scalable on-chip quantum networks.
