In this paper, we propose and experimentally validate a novel sparsity learning deep neural network nonlinear equalization method (SLDNN-NLM) for a 112-Gbps PAM4 signal using a 25-GHz externally modulated laser (EML) to transmit over 40-km standard single-mode fiber (SSMF) in O-band. Our proposed SLDNN-NLM can reduce computation complexity while still maintain the system performance. This method c...Show More

Volterra equalizations (VE) have delivered significant performance improvement on optical signals, but their extremely high demands on computation complexity severely impede the possibility of large-scale deployment in resource-constrained optical interconnects. In this paper, we propose and experimentally demonstrate a novel sparsity tuned elastic net-pruned Volterra equalization (SENVE) techniqu...Show More

Our investigation demonstrates that training patterns generated by Mersenne Twister pseudo-random number generator have potential to overcome the pattern effect. The resulting trained networks are capable of compensating the actual optical communication system response rather than merely predicting training signals.Show More

Today’s traditional, hierarchical, fullelectronic data centers cannot guarantee quality of service (QoS) for latency-sensitive applications or carrier-grade multitenancy.We propose cloud burst optical-slot switching (CBOSS), an intra-data center network architecture leveraging the original optical components and custom software- defined network (SDN) control to enable traffic engineering. In parti...Show More

Silicon Photonics Enabled Hyper-Wideband RF Receiver With >85% Instantaneous Bandwidth
Michael S. Eggleston;Chia-Ming Chang;Noriaki Kaneda;Kwangwoong Kim;Jeffrey H. Sinsky;Guilhem de Valicourt;Nicolas Chimot;Francois Lelarge;Tatsuo Itoh;Ming C. Wu;Young-Kai Chen
We demonstrate the first-ever silicon photonics enabled hyper-wideband RF spread-spectrum link. A hybrid III/V-silicon photonic mode-locked laser encoded with a four-channel silicon photonic phase encoder is used to generate optical carriers that coherently demodulate a received RF signal spanning an instantaneous bandwidth greater than 85% of the center frequency (12/14 GHz). This allows low-spee...Show More
Directly Reflectivity Modulated Laser
Po Dong;Anaelle Maho;Romain Brenot;Young-Kai Chen;Argishti Melikyan
Journal of Lightwave Technology
Cited by: Papers (13)
Directly modulated lasers (DMLs) have been widely employed in data centers and other short-reach interconnect applications, thanks to their low cost and low power consumption. Nevertheless, these lasers have small wavelength tuning ranges and are limited to produce only intensity-encoded optical signals through modulating the gain in the active region. Therefore, it is difficult to use them in met...Show More
