Research Description:

Dr. Hackl’s research focuses on complex infrastructure systems, intelligent risk and resilience assessments to climate change, as well as integrated solutions to future challenges facing our cities and society. His research interests lie at the interface between formal methods in network sciences and their integration with prevailing simulation methods, such as digital twins. He is particularly interested in developing scalable data analytics and machine learning techniques for spatial-temporal networks applied to dynamic processes in complex multiscale civil engineered systems to open and interconnect new perspectives for, e.g., modeling of usage, behavior, and performance; analysis of system integration; as well as detection of systemic risks in socio-technical systems. Another aspect of his work covers integrating these data-driven approaches with physics-based models to create digital twins that can learn from and update based on multiple data sources, as well as represent and predict the current and future conditions of their physical counterparts.

Research Description:

Research in my group, the Lightwave Communications Laboratory, is focused on investigating ultrafast optical techniques with application to communication networks and signal processing. My graduate students and I are working on several exciting and innovative research projects, which benefit from close collaborations with government and industrial research laboratories. A few examples of these projects are given below.

Physical (Optical) Layer Network Security:

Security in fiber optic networks is becoming of critical importance due to the nature and volume of the data that is transported. The optical layer of a network is itself vulnerable to attack by eavesdropping or jamming. My group is investigating several approaches using optical signal processing to counter these attacks, including optical steganography, all-optical encryption devices, anti-jamming techniques, and survivable network architectures.

Optical Code Division Multiple Access (CDMA):

Incoherent optical CDMA networks can offer several important system advantages that cannot be achieved with other multiplexing techniques such as TDM and WDM, including asynchronous access, soft blocking, privacy, scalability and variable quality of service. We are developing novel integrated technologies that will enable the realization of practical optical CDMA networks, which will be strong candidates for future broadband access networks.

Nonlinear Optical Signal Processing for Ultrafast Networks:

Based on nonlinear phenomena in semiconductor devices and nonlinear fibers, numerous optical signal processing functions can be achieved which can enhance the performance of ultrafast optical networks. We are studying novel devices and their applications, including optical thresholding, auto-correlation peak extraction, demultiplexing, physical layer security enhancement, and interferometric noise suppression

Optical Cancellation
of RF Interference:

Wireless communications systems often suffer from co-site interference, where the signal from a nearby transmission antenna interferes with simultaneously receiving a weak signal in a nearby frequency band. Multipath effects make this problem especially challenging. We are investigating optical and optoelectronic signal processing techniques to process RF signals from single antennas as well as phased arrays, enhancing their performance and enabling rapid reconfigurability.

The Photonic Neuron:

Using nonlinear optical and photonic materials, we have recently built a hybrid analog/digital signal processing device which performs all the functions of a physiological neuron, but one billion times fast. Our spiking neuron is faster and more efficient than a digital computer, and does not suffer from the noise accumulation of analog electronics. Using the photonic neuron, we are implementing sophisticated, ultrafast signal processing circuits and systems which emulate visual, auditory, and motor functions found in biological organisms.

With a high degree of interaction between government and industrial research laboratories, the Lightwave Communications Laboratory offers students an opportunity to be involved in the creation of technology for the next generation of optical signal processing, computing and communications systems.
