“…The o-Generator is rather implemented by a mode-locked laser, a key component used to generate a series of picoseconds pulses at GHz rates with high temporal stability, i.e. with very low jitter in the femtoseconds time-scale [7,19]. Therefore, these pulses can be used as the clock signal for the optical sampling and encoding steps.…”

“…Therefore, by using all-photonic DRoF more operations and signal processing centralization at the Central Station would be achievable. Although the e-DRoF technology is very useful and powerful, the main challenges are: ADC and DAC boards seem to exhibit an intrinsic limitation in their stability, limitations on "bit resolution x input frequency" product and data conversion rates of up to a few tenths of GSa/s, dispersions, nonlinearities (in electrical and optical domains), additive noise, integration of system and devices, size and system cost [3][4][5][6][7].…”

“…Alternatively, if an analogue RoF signal is already available, the o-DRoF-T comprises the optical sampler, the all-optical encoder and quantizer, only. After the encoder an additional circuit (thresholder or quantizer) is generally needed in order to enhance the contrast between the optical bits [7][8][9].…”

In this paper it is proposed and designed an alloptical 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-ofprinciple 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.

“…Optical quantising and coding allows higher processing speed as well as in principle low-cost implementations, avoiding parallel electronic ADC. In (Ikeda et al, 2006;Miyoshi et al, 2007) the periodical characteristic of the nonlinear optical loop mirror is employed for a 3-bit ADC at 10 Gsamples/s. Slicing of the spectrum broadened by SPM is exploited in ( Nishitani et al, 2008;Oda & Maruta, 2005).…”

“…As the optical communications and optical signal processing technology become mature, the optical ADC technology has been developed. Recently, one research group led by Jalali proposed the use of optical signal processing technology, so the high-speed analog input signal in time domain is extended, which reduces the bandwidth and achieves high sampling rate [7] .…”

All-optical analog-to-digital conversion (ADC) has been extensively researched to break through the inherently limited operating speed of electronic devices. In this paper, we use the photonic crystal fiber (PCF) for time-stretch (TS) analog-todigital (A/D) conversion system through generating low noise, linear chirp distribution and flat super-continuum (SC). Based on the radio frequency (RF) analog signal modulated to the linearly chirped super-continuum, the large-dispersion photonic crystal fiber is used for time-domain stretching.
