Absolute frequency references at 1529 nm and 1560 nm using modulation transfer spectroscopy

Y. Natali Martinez de Escobar, Silvana Palacios Álvarez, Simon Coop +3

We demonstrate a double optical frequency reference (1529 nm and 1560 nm) for the telecom C-band using ${}^{87}$Rb modulation transfer spectroscopy. The two reference frequencies are…
