Cutting-edge Photonics For Optical Data Transmission With Picosun


Picosun Group reports excellent results in development of state-of-the-art photonics with its ALD (Atomic Layer Deposition) equipment and solutions.

Photonic devices such as waveguide amplifiers and lasers are central components in optical data transmission, a key technology realizing our modern, connected, information-driven society.

Silicon-integrated photonics take the technology one step further, enabling a whole new generation of microelectronics where optical solutions overcome some of the key challenges of conventional technologies.

Erbium-doped waveguide amplifiers and lasers are the most potential candidates for signal generation and amplification for telecommunication wavelengths. To reach the maximum performance of these devices, the amount and spatial distribution of dopant erbium atoms in the host material must be carefully optimized and controlled. This is where ALD shows its unique strength and beauty.

At Aalto University, Finland, Picosun's customer Prof. Zhipei Sun's group at the Finnish national infrastructure Micronova, and his international collaborators, have now used Picosun's ALD technology to manufacture erbium-based silicon-integrated waveguide amplifiers with world-record performance(*).

“Silicon-integrated photonics, already employed by the leading companies in the field, are the future of microelectronics. We are very pleased of the performance of our PICOSUN® ALD equipment and the excellent quality of the Er:Al2O3 waveguide amplifiers manufactured with it. Customer support and consultancy from Picosun have always been there when we need it. ALD process is CMOS-compatible, further facilitating the integration of our waveguides into commercial chip production,” states Dr. John Rönn, the leading author of the results, from the Department of Electronics and Nanoengineering at Aalto University.

”ALD has been enabling disruptive future technologies since its invention. Picosun is happy to work with the leading experts in the field, such as our esteemed customers at the Aalto University. Our ALD solutions provide them the means to realize their groundbreaking work to develop yet more advanced communications and data transmission technologies for more connected, open, and integrated global society,” continues Mr. Edwin Wu, CEO of Picosun Asia Pte. Ltd

(*) The results were published in the journals ACS Photonics 3, 2040-2048 (2016) and Nature Communications 10, 432 (2019).

AngelTech Online Summit - Tuesday 19th May

The health and well-being of AngelTech speakers, partners, employees and the overall community is our top priority. Due to the growing concern around the coronavirus (COVID-19), and in alignment with the best practices laid out by the CDC, WHO and other relevant entities, AngelTech decided to postpone the live Brussels event to 16th - 18th November 2020.

In the interim, we believe it is still important to connect the community and we want to do this via an online summit, taking place live on Tuesday May 19th at 12:00 GMT and content available for 12 months on demand. This will not replace the live event (we believe live face to face interaction, learning and networking can never be fully replaced by a virtual summit), it will supplement the event, add value for key players and bring the community together – digitally.

The event will involve 4 breakout sessions for CS International, PIC International, Sensors International and PIC Pilot Lines.

Key elements of the online summit:

  • Covering key topics of the industries
  • Live 3 hour online summit
  • 10 minute presentations – learn from experts in the industry
  • Recorded product demos
  • Live audience questions
  • Enhanced discussion and audience interaction
  • Video panel sessions
  • Sponsors digital booth (intro video, company content, lead generator, facilitate one on one video meetings with attendees)
  • Live private video meetings between two or more attendees
  • After the live event, monthly keynotes to drive traffic to the event 24/7, 365

Innovation is in AngelTech’s DNA and we are leveraging this strength to bring you an immersive and inspiring online event without the risk of travel during this uncertain period.
