The new multimode optics - self-configuring circuits and fundamental limits for photonic structures

Tutorial talk at ePIXfab 8 workshop, Gent, July 6, 2023 Silicon photonics allows circuits with large numbers of elements that offer many new capabilities, but we need reasonable ways to design and control such complex interferometric circuits. Fortunately, some very convenient architectures, mathematics and algorithms allow simple control, including even self-configuring circuits that can adapt… Read more The new multimode optics - self-configuring circuits and fundamental limits for photonic structures

Self-configuring photonic circuits and limits in optics

Keynote talk at Photonics West, 2023 – “Self-configuring algorithms, topologies and fundamental limits for photonic circuits and structures” Micro- and nano-fabrication allow new optical systems well beyond previous conventional optics. These possibilities cause us to think of optics quite differently. One approach uses “circuits” with topologies and configuration algorithms. Some such topologies support algorithms allow… Read more Self-configuring photonic circuits and limits in optics

Optical interconnects to chips - why and how

High-performance information processing is increasingly limited by getting enough information on and off electronic chips. Optics can solve the limiting density and power problems, though we need different approaches from previous optical communication systems. This tutorial given at the IEEE Photonics Conference explains why, and how we can transform performance. Invited Tutorial, IEEE Photonics Conference,… Read more Optical interconnects to chips - why and how

Getting to femtojoule optics – what physics and what technology?

This invited talk, given by David Miller at the Optical Fibers Conference (OFC) 2021 in the Symposium on Emerging Photonic Technologies and Architectures for Femtojoule per Bit Optical Networks, explains how we get the total energy per bit communicated into the femtojoule range. This would transform the power dissipation of large systems like data centers.… Read more Getting to femtojoule optics – what physics and what technology?
