Coherent 100 Gb/s optical communications link

This PhD project deals with the investigation of coherently detected, DQPSK systems. The goal of the project is the investigation, conception and assessment of overall performance of a DQPSK coherent receiver, employing digital signal (DSP) processing algorithms for phase noise estimation and compensation. The project will also consider the incorporation of DSP for compensation of transmission impairments due to chromatic dispersion, polarization mode dispersion, and optical filtering cascading. At the end of the project, the aim is to layout the benefits of coherent detection receivers for DQPSK optical transmission links with special emphasis on transmission impairments.
The project is a joint research effort between the Systems Competence Area at DTU and Tellabs Denmark within the framework of the Photonics Academy of Denmark. Therefore, the current PhD project entails rich possibilities for cross-disciplinary work, especially covering the path from system specifications, theoretical limits, and implementation issues in realistic optical networking scenarios in cooperation with Tellabs.

The candidate should have a master’s degree in EE engineering, engineering physics or equivalent and an excellent background in telecommunications, optical communication, and digital signal processing. Excellent communications skills in English are mandatory and a proved capability for autonomous, creative and innovative work.
The candidates for the PhD degree are subject to academic approval, and the candidates will be enrolled in one of the general degree programmes of DTU. Information about the general requirements for enrolment and the general planning of the scholarship studies is included in the general rules of DTU, which may be obtained by application to the PhD programme office at tel: +45 4525 1176 or +45 4525 1177.

The salary and appointment terms are consistent with the current rules for PhD degree students.
For further information regarding the position, please contact: Associate professor Idelfonso Tafur Monroy, e-mail: [email protected] All interested candidates irrespective of age, gender, race, religion or ethnic background are encouraged to apply.
