Pascale Senellart’s research group at University Paris Saclay's Centre for Nanoscience and Nanotechnology (CNRS) develops semiconductor devices for optical quantum technologies. ‘We study artificial atoms, quantum dots,
that are perfect single photon emitters. We developed a unique technology that allows us to collect very efficiently the emitted photons – a long-sought goal for quantum technologies.’ Quandela has been commercialising these
single photon sources since 2017, and since 2020 it has been developing a photon-based quantum computing platform. ‘The next

The shrinking of optical combs is a huge opportunity, believes Pilot Photonics’ CTO Frank Smyth. ‘Because they have tended to be large and bulky, they have remained as lab instruments for the most part. Now optical combs can be delivered as a chip- scale component, making them suitable for high-volume applications for the first time.’ Smyth sees optical communications and mmWave photonics as massive opportunities for these PIC-based comb lasers, as well as lidar, optical sensing & spectroscopy and precision timing. ‘Continuing to scale coherent optical transceiver bandwidth is becoming

increasingly challenging,’ said Smyth, however. ‘It is getting more and more challenging due to signal integrity issues, and the sheer cost and investment required to switch to new silicon nodes, and design ever faster digital signal processors. Integrated comb lasers carry more data than a single mode laser can and help to overcome this challenge by parallelising the data stream.’ You can find Smyth online at

Congratulations, Frank!
“Frank, as co-founder of Pilot Photonics, has been the driving force, since the company’s inception, to develop its unique optical comb technology into a commercial reality. He secured numerous prestigious European funded projects to support his vision and has led the design of an integrated optical comb laser, which is uniquely suited
to enable, among other things, the next generation of optical communications systems, the backbone of all telecommunications and data communications networks.”

big thing will be cloud access to a photonic quantum computing machine,’ said Senellart. ‘We will progressively increase the number of qubits, enabling applications such as quantum machine learning algorithms.’ ‘Our next big challenge is the development of efficient sources of highly entangled multiple photons. We have just demonstrated a first proof of concept generation of three- particle entanglement at a high rate.’ She said they now need to bring the number of entangled photons and quantum fidelity up. Senellart is on Twitter @Senellartqd. She plans to attend CLEO in May 2023.
