| Zusammenfassung | Due to the increased bandwidth requirements of wireless receivers, the electronics-based analog-to-digital conversion (ADC) can be seen as a bottleneck. Photonics-based ADC, instead, provides much higher signal integrity and processing bandwidth. Hence, photonic-assisted ADCs may offer a solution to process 6G and beyond signals, that aim for 1 Tbit/s peak data rates. Here we present results for integrated optical cascaded ring modulators (RMs) that enable a compact, energy-efficient signal processing of broadband wireless signals. The received signal is converted to the optical domain with a first RM. Then, it is sampled with another RM by orthogonal sampling with optical sinc-pulse sequences (SPS) in N parallel branches. The SPS generation and sampling occur simultaneously in the RM. No aperture jitter is added as our optical sampling relies on multiplication instead of switching. A proof-of-concept with 18 GHz electro-optic bandwidth RMs demonstrates a 36 GSa/s Nyquist sampling rate with a 12 GHz oscillator (N = 3). Recent RM designs, surpassing 100 GHz bandwidth, may enable the reception of 1 Tbit/s wireless signals in real time. |
