Abstract :
This paper discloses an Analogiser able to carry out digital to analogue conversion of the optically digitised Radio-over-Fibre signals. The Analogiser comprises many interconnected optical circuits based on the Sagnac interferometric rings with an inserted semiconductor optical amplifier. Numerical simulation results are shown for 2.5 GHz sampling rate and 4-bit resolution. The designed circuits are compact, thus enabling optical integration and require optical peak power control in the ~mW range.
