According to a report by Maims Consulting, Finnish equipment manufacturer Picoson has recently achieved remarkable results in the development of first-class photonics technology with its ALD (Atomic Layer Deposition) equipment and solutions.

Optical devices such as optical waveguide amplifiers and lasers are the core components of optical data transmission, as well as one of the key technologies for realizing social modernization, interconnection and information driving.

Silicon photonic integration technology has promoted the further development of optical devices, and optical solutions have overcome some of the key challenges in traditional technologies and opened a new era of microelectronics technology.

Erbium-doped optical waveguide amplifiers and lasers are the most potential candidates for signal generation and communication wavelength amplification. In order to obtain the best performance of these devices, the quantity and spatial distribution of erbium atoms in the host material must be strictly optimized and controlled. Only ALD technology can meet the above requirements.

Professor Sun Zhipei of Aalto University in Finland is also one of Picosun’s customers. He has now adopted Picosun’s ALD technology and has worked with international partners in Micronova (Finnish National Micro and Nano Technology Research Infrastructure, developed by Finnish VTT Technology Research). The center and Aalto University jointly developed a world record high-performance erbium-doped silicon photonic integrated waveguide amplifier.

"Silicon photonic integration technology has been adopted by enterprises in the optical field, and is the future development direction of microelectronics technology. We are very satisfied with the performance of the PICOSUN®ALD equipment and the excellent quality of the Er:Al2O3 optical waveguide amplifier manufactured by it. When encountering problems At the time, Picosun’s customer support and consulting staff are always ready to provide us with high-quality services. Dr. John Ron of the Department of Electronics and Nano-Engineering of Aalto University said: “ALD technology is compatible with CMOS process, which further promotes our optical waveguide chip Commercial production. ".

"Since the invention of ALD technology, it has always been a booster for disruptive technologies in the future. Picosun is very happy to work with experts in this field. For example, Aalto University is our important customer. Our ALD solution provides them with innovation. In order to develop more advanced communication and data transmission technologies to realize a more interconnected, open and integrated global society.
