Description
The Photonics laboratory at the Microtechnology and Nanoscience Department (MC2) is a dynamic and creative group with about 30 members working in an international and collaborative atmosphere. We perform both curiosity-driven and applied-research in the areas of optoelectronics, nanophotonics, and fiber optic systems. We enjoy a state-of-the-art laboratory for fiber-optic communications and have access to in-house clean-room facilities to manufacture photonic devices engineered at the nanoscale. Part of our recent research efforts focus on Next-generation optical communication systems featuring ultra-fast data rates (>1 Tb/s); Optical fiber amplifiers with world-record noise figures (1 dB); and ultra-high-repetition-rate (>10 GHz) optical frequency comb technology.
An optical frequency comb is typically produced by an ultrashort laser pulse train, whose spectrum consists of a series of discrete equidistant lines spanning over a broad bandwidth. The outstanding phase-noise performance of optical frequency combs has revolutionized the fields of optical synthesis and metrology. The applications of this Nobel-Prize-winning technology range from optical clocks to the synthesis of ultra-pure microwave signals. This project deals with the development of emerging and compact optical frequency comb platforms delivering ultra-high-repetition rates (10-100 GHz) and the study of their suitability for applications in optical communication systems. We will study two main platforms, i.e., electro-optic frequency comb generators made of lithium niobate modulators, and integrated silicon nitride microring resonators. The work is 50% experimental and 40% numerical modeling. It involves testing of chip devices, development of electro-optic comb generators and realization of applications. You will also have room to contribute with your own ideas. The PhD student position is limited to 4 years. The majority of your working time is devoted to your own research project. In addition, the position will normally include 10% departmental work, mostly teaching duties.
Requirements
By the incorporation date, the applicant should have a Master’s degree (or equivalent) in Applied Physics, Engineering Physics, Electrical Engineering or similar, with especialization in Photonics. Experience with either silicon photonics, ultrafast optics, optical communications is a merit. You must be fluent in English.
