Postdoc in CMOS Integrated Circuit Design for Electronic-Photonic Integration - DTU Electro

Are you an integrated circuit designer who wants to bring CMOS electronics and photonics together in a single chip assembly?

In the project EPIC (Electronic-Photonic Integration for Energy-Efficient Information Processors), funded by the Independent Research Fund Denmark, we are developing thin-film lithium niobate photonic circuits with custom electronic control chips flip-chip bonded onto them. As a postdoc in our team, you will design the electronics that drive, stabilize, and modulate our photonic devices.

Cavity-based electro-optic modulators in lithium niobate are compact and energy-efficient, but their resonances shift with temperature and fabrication variations. EPIC addresses this by building sensing and feedback control into the electronics, with the aim of stable, large-scale photonic circuits for energy-efficient information processing. Furthermore, the EPIC project includes a cavity-based electro-optic modulator driven by radiofrequency (RF) CMOS control signals. You will work with Professor Per Lynggaard’s IC design team and Associate Professor Mikkel Heuck’s photonics team at DTU Electro. The project combines custom chip design with flip-chip bonding at DTU Nanolab.
