Abstract : In this paper it is proposed and designed an all-optical Sampler o-Sampler intended to be part of future optical Digitising Radio-over-Fibre o-DRoF transceivers. It is based on the Semiconductor Laser Amplifier Loop Mirror SLALOM configuration thus using the nonlinearities of a semiconductor optical amplifier SOA in cross-switching regime. The proof-of-principle is established by computer simulations using 500 MHz analogue signal and 2.5 GS-s sampling pulses both in the C-band. The proposed o-Sampler outputs real-time generated optical samples from an analogue RoF signal. The simulated device is rather compact,polarisation independent, potentially optically integrable and requires few mW of sampling peak power.
