“…Although photonic ADCs have been demonstrated with a wide variety of architectures [1], most of the best performing designs can be described as a variation of the generalised model shown in Fig. 1(a) [2,3,9,10]. This model is generalised in the sense that it contains the minimum active components required to implement a photonic ADC: a pulsed laser source as the optical sampling device, an electro-optic modulator to map the input signal onto the optical pulse train, followed by a bank of N channels containing a photoreceiver and electronic sub-ADC [8].…”

“…that detect subsets (either in the time [2,9] or frequency [3,10] domains) of the incoming signal in parallel at a fraction of the aggregate sampling rate. The signal is then reconstructed digitally to obtain the full rate signal at the much higher resolution offered by such optical techniques.…”

“…Note that actual photonic ADCs will contain additional passive components: e.g. a pulse interleaver [2], filters and gratings [10] or dispersive elements [9] that are not shown in the generalised model of Fig. 1.…”

“…In terms of power consumption, the effect of these passive components is to simply reduce the effective wall plug efficiency of the optical source. Some may even have multiple optical sources [3,10], which will simply increase the value of the optical power term. The required optical source power P opt is set by the power required to achieve a desired SNR, given the noise limits set by shot and thermal noise for optical frequency ν and Planck constant h…”

“…In recent years, many optical ADC schemes have been proposed and demonstrated, which can be divided into four major types [1]: photonic assisted (PA) ADC [3,4], photonic sampled (PS) ADC [2,5,6], photonic quantized (PQ) ADC [7] and photonic sampled and quantized (PSQ) ADC [8][9][10][11][12][13][14][15][16][17]27]. PA, PS and PQ ADCs still require several high speed electronic ADCs for either sampling or quantizing, resulting in additional power consumption and system complexity.…”

In this paper, an on-chip photonic sampled and quantized analog-to-digital converter (ADC) on thin-film lithium niobate platform is experimentally demonstrated. Using two phase modulators as a sampler and a 5×5 multimode interference (MMI) coupler as a quantizer, an 1 GHz sinusoidal analog input signal was successfully converted to a digitized output with a 20 GSample/s sampling rate. To evaluate the system performance, the quantization curves together with the transfer function of the ADC were measured. The experimental effective number of bits (ENOB) was 3.17 bit. The demonstrated device is capable of operating at a high frequency up to 70 GHz, making it a promising solution for on-chip ultra-high speed analog-to-digital conversion.

Low-Bandwidth Photonics-Assisted Receiver for Broad-Bandwidth Wireless Signals

et al. 2023

This paper introduces a photonics-assisted receiver that enables the reception of high-bandwidth wireless signals with low-bandwidth electronics. The receiver down-converts the input signal into parallel low-bandwidth sub-signals, employing photonics-based orthogonal sampling. This sampling is based on a multiplication and not switching, so, it does not introduce additional aperture jitter. Therefore, the photonics-assisted analog-to-digital converter (ADC) converts the wireless signal with a higher signal-to-noise-and-distortion ratio (SINAD), which improves the Q-factor for the detection. This Q-factor improvement is especially high, when the orthogonal sampling is carried out with low-jitter oscillators. Compared to the direct detection with 30 GHz, the simulation demonstrates a 2.2 dB Q-factor enhancement for the detection of a 30 GHz signal, with 10 GHz electronics. The same improvement is revealed in the experiment for the detection of 12 GHz signals with 4 GHz electronics.
