Mona Jarrahi
Organisation: UCLA Role: Professor of electrical and computer engineering
Based in: Los Angeles, California, USA
Mona Jarrahi has made significant contributions to the development of ultrafast electronic and optoelectronic devices and integrated systems for terahertz, infrared, and millimetre-wave sensing, imaging, computing, and communication systems. The outcomes of her research, involving use of novel materials, nanostructures, and quantum structures as well as innovative plasmonic and optical concepts, have appeared in more than 250 publications and 200 invited talks. In November 2022, Jarrahi was named
Clément Javerzac-Galy
Organisation: Miraex Role: Co-founder Based in: Lausanne, Switzerland
While using devices for fundamental quantum physics in a cryostat (a very cold fridge) during his studies, Javerzac- Galy came up with the idea for the core technology of the company he co-founded in 2019, Miraex. He wanted to develop simple versions of those microdevices to help carry out measurements in extreme conditions where it is otherwise impossible. Miraex develops photonic solutions for
next-generation sensing, networking, and computing. Its hardware platform is based on semiconductor wafer-level processes, and the company develops its own designs and

owns the full manufacturing process for its sensors, transducers and converters. Javerzac-Galy holds two patents and
has numerous publications exploring semiconductor materials and quantum applications. During his time at EPFL, he won the IBM Quantum Best Paper Award, the OSA Student Chapter Excellence Prize, and was a finalist for the Emil Wolf Student Paper Competition. Outside of research and business,
Javerzac-Galy has been a boy scout since the age of five, which he says taught him values that impact who he is today.
Nemanja Jovanovic
Organisation: California Institute of Technology
Role: Lead Instrument Scientist
Nemanja Jovanovic’s day job at Caltech’s Optical Observatory and Exoplanet Technology Laboratory is to develop extremely customised astronomical instruments for observatories. So what technologies is he looking to to do so? ‘Photonic technologies optimised to
generate signals, which can be used to drive wavefront control loops for adaptive optics systems and fine phasing in the form of fringe tracking are receiving a lot of attention,’ he said. ‘Such systems allow for wavefront control free from non-common path and chromatic
errors, potentially delivering superior coupling efficiency, and hence an improved overall system efficiency, greater stability, and higher sensitivity.’ Jovanovic believes efficient integration
with detectors and scaling to high pixel counts will be the biggest challenge over the next decade: ‘Multi-pixel detectors are extremely costly and have a form factor mismatch with the output of integrated photonic circuits. Developing approaches to efficiently route the light from planar circuits to multi-pixel arrays will enable the realisation of integrated instruments.’
