Postdoc in Nonlinear Integrated Silicon Photonics

Danmarks Tekniske Universitet

Lyngby-Taarbæk, 1 stilling

DTU Fotonik works with all areas of photonic engineering, including a strong focus on optical communications consolidated by combined activities between the ‘High Speed Optical Communications’ and ‘Nanophotonic Devices’ groups.



Within recent years, these groups have demonstrated world records in optical signal processing (OSP) speeds utilizing silicon photonic waveguides. However, in the telecommunication wavelength band crystalline silicon (c-Si) material suffers from two-photon absorption (TPA), which limits the performance of the silicon platform for high-speed and energy efficient OSP. For this reason, people are looking towards utilizing e.g. amorphous silicon (a-Si) which shows enhanced non-linear properties and low TPA, but presently this platform is being questioned due to long-term stability issues of the material. Silicon-rich-nitride (SRN) and –oxide (SRO) materials are other group IV materials being investigated for their non-linear properties and time will show how far these materials can be utilized with respect to OSP .



We are now seeking a Postdoc to investigate alternative group IV material platforms for OSP such as a-Si, SRN, and SRO partly in connection with the newly established centre of excellence Silicon Photonics for Optical Communications (SPOC) and partly funded by the Danish National Research Foundation and funded by the DFF Sapere Aude Advanced Grant project NANO-SPECs. Facilities at the National cleanroom Danchip (http://www.spoc.dtu.dk and about DTU Fotonik on http://www.fotonik.dtu.dk/devices.
