Industrial PhD - Picosecond Pulse Sources for Quantum-Dot Excitation (PULSE-Q)

At Phanofi, we are developing next-generation photonic integrated circuits that power AI infrastructure, datacentres, and quantum communication systems. We are looking for a highly motivated Industrial PhD candidate to join the PULSE-Q project, a 3-year research collaboration between Phanofi and The Technical University of Denmark (DTU) Department of Electrical and Photonics Engineering (DTU Electro), co-funded by Innovation Fund Denmark. As an Industrial PhD researcher, you will work at the intersection of integrated photonics, quantum technologies, and ultrafast optics. You will help develop compact photonic-chip-based picosecond pulse sources for quantum-dot excitation, enabling scalable quantum technology. This role offers a unique opportunity to combine academic research with real-world product development while working closely with leading researchers and industry experts. The position is open to both national and international applicants. About the Project Quantum dot based single photon sources require highly controlled optical pulses with picosecond pulse durations for efficient single-photon generation. The PULSE-Q project aims to develop a compact, tunable, chip-integrated picosecond pulse source built on state-of-the-art photonic integrated circuit (PIC) technology. Existing solutions are often expensive, bulky, or difficult to integrate. In this project, you will investigate and advance Phanofi's pulse source to enable compact, low-cost, and scalable photonic pulse sources suitable for future quantum systems. What You'll Be Doing Photonic Design & Simulation: Design and simulate novel photonic components and integrated photonic building blocks using photonic simulation tools and analytical modelling techniques. PIC Development: Develop PICs that are compatible with UV-lithography methods and enable scalable production. Investigate alternative integrated-photonics material platforms for high-performance PICs. Fabrication & Tape-out: Prepare fabrication-ready mask layouts and collaborate closely with DTU Nanolab during chip fabrication and process development. Characterization & Testing: Perform optical and electrical characterization of fabricated devices, including optical transmission measurements, and RF characterization, and, thermal tunability analysis Pulse Source Development: Design, build, and characterize pulsed laser systems for O-band, C-band, and NIR operations. Support PCB design and FPGA development activities for pulse source system. Innovation: Investigate novel pulse generation concepts and explore their applications in quantum technology and ultrafast photonics. Scientific Dissemination: Publish research findings in leading journals and present results at international conferences such as CLEO, SPIE Quantum West, and ECOC.
