Room-temperature 1.54 $\mu$m photoluminescence of Er:O${}_x$ centers at extremely low concentration in silicon

Michele Celebrano, Lavinia Ghirardini, Paolo Biagioni +11

The demand for single photon sources at $\lambda =1.54\mu$m, which follows from the consistent development of quantum networks based on commercial optical fibers, makes Er:O${}_x$ centers…
