Abstract :
The possibility of building multiwavelength coherent communication systems based on low-cost semiconductor lasers in the 0.8 μm range locked to rubidium linear absorption is investigated. The values of frequency offset between the resonances of both the D2 (780 nm) and D1 (794.7 nm) lines are considered. A simple two-carrier FDM set-up using three resonances of the D2 line is presented and the optical frequency offsets are measured
