Postdoc positions (2) within Theory, Fabrication, and Optical Characterization of Nanocavities and Chip-Scale Spectrometers The Photonic Nanotechnology group at the Department of Electrical and Photonics Engineering at DTU conducts research at the forefront of nanophotonics within both fundamental and applied research on silicon nanodevices. With a newly funded ERC Consolidator grant focusing on deep subwavelength optical cavities and to strengthen ongoing innovation projects we are now inviting applications from postdoctoral researches who have demonstrated excellent research in their PhD, a previous postdoc position, or in industrial research and development. Common to all projects in our group is that they use silicon membranes and our unparalleled expertise in nanolithography and etching as the experimental platform ensures strong synergies across projects with the different research goals. Our interdisciplinary research addresses multiple areas including quantum optics, solid-state physics, nanotechnology, mathematical modelling, inverse design, integrated photonics, semiconductors, nanofabrication, spectroscopy, mechanical design, photonics packaging, and more. Our experiments benefit from our access to DTU Nanolab – one of the world’s most advanced academic cleanrooms. We emphasize strong interactions between experiment and theory, independent thinking, and team spirit. The first project concerns the study of bowtie silicon cavities, which we recently employed to demonstrate the world’s smallest optical dielectric cavity, see, and . We have recently realized cavities which enhance the light-matter interaction by a Purcell factor or nearly 1 million and we are now embarking on exploiting this extreme and unexplored regime of light-matter interaction for optical nonlinearities, quantum light sources, and optomechanical interactions. The second project aims to develop chip-scale nanoelectromechanical spectrometers for use in food spectroscopy, wearables, and beyond, which we are pursuing in a large-scale innovation project with several industrial partners. Nanoelectromechanical actuation allows reducing the power consumption of chip-scale sensors by orders of magnitude compared to the prevailing thermo-optic control and offers in addition a playground for physics and engineering combining photonics, mechanics, and electronics at the nanoscale. Responsibilities and qualificationsThe successful candidates will be responsible for either nanofabrication, theory, or optical experiments in one of the two projects mentioned above. The details, responsibilities, and tasks of the postdoc positions will be tailored to the qualifications and interests of the applicants but will revolve around these headlines. Most importantly, we seek highly motivated and excellent individuals with an interest in teamwork and research at the highest international level. The main responsibilities and tasks include: Responsibility for driving either nanofabrication, theory, or optical experiments within either subwavelength cavities or nanoelectromechanical spectrometers. Active contribution to the daily supervision and training of PhD students as well as students at other levels. Active contribution to the development of new research ideas. The present positions are fully funded but we also support candidates who wish to apply for their own funding through the MCSA programme or national research funding programmes, or, depending on seniority, ERC starting grants or similar. As a formal qualification, you must hold a PhD degree (or equivalent). We offer DTU is a leading technical university globally recognized for the excellence of its research, education, innovation and scientific advice. We offer a rewarding and challenging job in an international environment. We strive for academic excellence in an environment characterized by collegial respect and academic freedom tempered by responsibility. Salary and terms of employment The appointment will be based on the collective agreement with the Danish Confederation of Professional Associations. The allowance will be agreed upon with the relevant union. The period of employment is 2 years. Starting date as soon as possible according to mutual agreement. You can read more about .
