EFFECT Photonics

Fabless PICs for coherent optical communications

Overview

EFFECT Photonics designs and manufactures photonic integrated circuits (PICs) for optical communications, using Indium Phosphide to monolithically integrate lasers, modulators, and detectors on a single chip. Its products, like integrable tunable laser assemblies, power coherent optical transceivers that use dense wavelength division multiplexing (DWDM) for high-speed data center and telecom links. The company operates fablessly, partnering with foundries for scalable production and leveraging in-house digital signal processing expertise gained from a Viasat DSP team acquisition. Its goal is to deliver compact, energy-efficient, high-bandwidth optical components at scale to support data centers, 5G networks, and telecom infrastructure.
