We have carefully examined how amplified spontaneous emission noise affects optical quantization using soliton self-frequency shift for photonic analog-to-digital conversion in terms of integral nonlinearity and the influence of number of bit.
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 propose and demonstrate the all-optical M-ary ASK signal demultiplexer based on photonic analog-to-digital conversion with bitwise signal allocation. Experimental result shows that the quaternary ASK signal can be successfully demultiplexed into two 25 Gb/s OOK signals
