Heterogeneously Integrated ITO Plasmonic Mach-Zehnder
Interferometric Modulator on SOI

By heterogeneously adding a thin material layer of indium tin oxide to the silicon photonic waveguide chip, we have demonstrated an optical index change 1,000 times larger than silicon. Unlike many designs based on resonators, this spectrally broadband device is stable against temperature changes and allows a single fiber-optic cable to carry multiple wavelengths of light, increasing the amount of data that can move through a system.

“We are delighted to have achieved this decade-long goal of demonstrating a GHz-fast ITO modulator. This sets a new horizon for next-generation photonic reconfigurable devices with enhanced performance yet reduced size,” said Dr. Volker J. Sorger, Founder and President of Optelligence LLC.

Breaking the Size and Speed Limit of Modulators for Next Generation Internet and Communication Networks

Unlike the current paradigm in electronic machine learning hardware that processes information sequentially, this processor uses the Fourier optics, a concept of frequency filtering which allows for performing the required convolutions of the neural network as much simpler element-wise multiplications using the digital mirror technology

"This massively parallel amplitude-only Fourier optical processor is heralding a new era for information processing and machine learning. We show that training this neural network can account for the lack of phase information," said Dr. Volker J. Sorger, Founder and President of Optelligence LLC.

"This prototype demonstration shows a commercial path for optical accelerators ready for a number of applications like network-edge processing, data-centers, and high-performance compute systems," said Dr. Hamed Dalir, Co-founder and CTO of Optelligence LLC.

AI Machines Can Learn Unsupervised at Speed Of Light

“The performance of the light neural network (tensor) processing units TPU was found to be three orders higher than a regular electrical TPU, with photons also found to be an ideal match for computing node-distributed networks as well as engines performing advanced tasks with high throughput at the edge of a network, like 5G.” said Dr. Volker J. Sorger, Founder and President of Optelligence LLC.

Strainoptronics: A New Way to Control Photons

We have discovered a new way to engineer optoelectronic devices by stretching a two-dimensional material on top of a silicon photonic platform. The amount of strain these semiconductor 2D materials can bear is significantly higher when compared to bulk materials for a given amount of strain. They also note these novel 2D material-based photodetectors are 1,000 times more sensitive compared to other photodetectors using graphene. Photodetectors capable of such extreme sensitivity are useful not only for data communication applications but also for medical sensing and possibly even quantum information systems. said Dr. Volker J. Sorger, Founder and President of Optelligence LLC.
