Enhanced optical phase shift efficiency using multi-mode-interference devices

In person: 29 September 2021 • 2:50 PM - 3:10 PM BST | Boisdale 1

Abstract

We propose and demonstrate a device design for power reduction in optical phase shifter based on Mach-Zehnder interferometer (MZI). The multimode region of a 2x2 Multi-Mode-Interferometer (MMI) is used as the modulation region. The light is circulated through the same multimode region twice and therefore utilizes the already present change in temperature/carriers leading to additional phase change, and an increase in efficiency compared to conventional Single-mode waveguide based phase shifting components. The devices show low insertion loss penalty and do not add any fabrication complexity.
