We experimentally realize seamless operations with below 100-fs timing jitter in a 10-GSample/s 3-bit photonic analog-to-digital converter (ADC) with an input 2.5-GHz sinusoidal electrical signal. To address the energy efficiency, it is necessary to explore some serial approaches to get most operations in a photonic ADC done before serial-to-parallel conversion to save the number of devices. To press...
We report the attempt of 10-GS/s 5-bit optical quantization using soliton self-frequency shift and spectral compression. Experimental results show sampling rate transparency of the proposed scheme.
Attention will be paid to cooperative use of analog and digital signals to make a full use of each excellent feature. All optical analog-to-digital conversion has been investigated to solve problems due to electrical bandwidth limitation. In this paper, our proposed all optical A/D conversion is briefly reviewed and our recent trial for securing high power-stability of optical pulses for quantization...
