ESPOO, Finland, March 29, 2020 /PRNewswire/ -- 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).
