PhD scholarship in Nano-Imprinting on Chalcogenide MIR-Fiber End-Facets to Reduce Coupling Losses
Danmarks Tekniske Universitet
Lyngby-Taarbæk, 1 stilling
The strategic research project ShapeOCT will establish a strong Danish research environment in the development and application of ultra-high resolution OCT (optical coherence tomography) imaging equipment for rapid contactless studies of skin cancer in an international collaboration between the Technical University of Denmark, Bispebjerg Hospital and the company NKT Photonics, as well as several strong international partners, such as Harvard Medical School in USA. The system uses as a light source a supercontinuum laser whose enormous spectral bandwidth and high intensity means that an axial resolution of only 2 micron can be achieved.
The PhD studentship will be part of a ShapeOCT work package responsible for the development of techniques for nano-imprinting on chalcogenide fiber end-facets to reduce coupling losses.
Responsibilities and tasks
The PhD studentship will comprise the following elements:
•Master origination in Si by use of state of the art nanolithography tools, such as electron beam lithography, UV and DUV lithography, dry and wet Si etching.
•Electroforming of nickel stamps from Si masters.
•Development of techniques for nanoimprinting on fiber end-facets.
•Finite element (FE) modelling of the coupling losses for specific imprint patterns.
•Topological characterization of samples and intermediate formats by SEM, AFM, and optical interference profilometry.
•Functional characterization of samples by employment of optical spectroscopy in the mid-infrared spectrum (MIR).
•Data analysis and comparison to theoretical models.
•Dissemination of results by writing of manuscripts for publication in scientific journals and presentations at conferences.
•Teaching assistance and undergraduate student supervision; about 220 hours in total over 3 years will be requested from the student.
•Coursework, summer- and winter-schools corresponding to 30 ECTS points must be included in the PhD studentship.
•Participation and status presentations at weekly group meetings, supervisor meetings, and general project meetings is anticipated from the student.
