Understanding photoluminescence in semiconductor Bragg-reflection waveguides: Towards an integrated, GHz-rate telecom photon pair source

Silke Auchter, Alexander Schlager, Hannah Thiel +7

Compared to traditional nonlinear optical crystals, like BaB${}_2$O${}_4$, KTiOPO${}_4$ or LiNbO${}_3$, semiconductor integrated sources of photon pairs may operate at pump wavelengths muc…
