Lightwave Logic in the US has moved to atomic layer deposition (ALD) for photonic chips following the acquisition of Chromosol in the UK.
“We achieved our goals with foundries in 2022 focusing on front-end PDKs to fabricate polymer modulators onto silicon wafers,” said Dr. Michael Lebby, CEO of Lightwave Logic.
“Not only did we fabricate polymer modulators that resulted in great performance, but we are also working with our foundry partners to optimize modulator performance results. This will position us very well for our goals in 2023 In,” he said.
“In 2022 we started working with ALD for chip-scale packaging, and this type of packaging can be completed using foundry back-end PDKs [and] have moved quickly to position ourselves strongly with ALD through focused patents, as well as a recent acquisition of Chromosol’s state-of-the-art ALD fabrication and deposition process.”
The extremely low temperature ALD process develop by the spinout of Queen Mary University London effectively hermetically seals polymer devices that have been prepared for high volume manufacturing. The ALD intellectual property acquisition will improve the back-end process PDKs for chip-scale packaging of the polymer modulators.
He expects to demonstrate a high speed optical transceiver using the polymer materials in 2023. It has been working with the Karlsruhe Institute of Technology and SilOriX on a silicon slot modulator using the polymer material with record performance.
It has also achieved a second world record demonstration with a 250GHz super high bandwidth electro-optical-electrical link through another partner collaboration using Polariton’s high-speed plasmonic modulators containing our proprietary Perkinamine chromophores and ETH Zurich’s high-speed graphene photodetectors.
“We continued working with our packaging partner in 2022 to package our polymer modulators into traditional gold-boxes for reliability testing and evaluation. This will continue into 2023 focusing on expanding our reliability data set, which is something end-users in the data-communications industry are asking us to see as a next step,” he said.
“We have intensified our reliability testing and expanded our laboratory space by approximately 9,000 square feet. We continue to look for world class technical staff and have recently hired multiple PhD level lab staff to focus exclusively on reliability testing – all with the goal of expediting data sets that are needed for commercialization with end-users. We expect to have this data in hand during 2023, laying the foundation for performance demonstrations in 2023.”
“Looking ahead to 2023, we expect to see our first licensing agreement for our polymers, in addition to world class performance demonstrations that we expect will show end-users that our technology is not only exciting, but will enable their business models to be more competitive for optical networking and internet system design.
“There are significant additional milestones in the works that we aren’t yet ready to discuss, but taken as a whole, we are incredibly confident in the direction of our business and in our team’s ability to make our next-generation technologies truly ubiquitous in the global internet infrastructure of the future,” he said.
