Start: October/November 2022
Duration: 3 years
Laser-based high-precision frequency metrology systems are considered as one of the key building blocks for future novel optical payloads and missions. It will find its applications in a wide range of optical instruments surpassing performances of conventional approaches.
One of the major challenges is the integration of an end-to-end signal processing chain starting from analogue detection and modulation to digital closed-loop control as well as an overarching system control unit. The task will be to take care of the opto-mechanical aspects of a pulsed laser system, the optical control units used to generate the signal to be controlled, and the former mentioned control system architecture and performance that drives the final instrument and system performance.
Such digital architectures are meanwhile employed in all commercial ground systems. For an application in space, the degree of automation and build-in evaluation capabilities will exceed ground-based systems significantly. At the same time, power consumption, footprint and robustness are driving aspects besides the sole performance. Therefore, the opto-mechanical and electronic aspects will be optimised with system aspects in mind to achieve a functional optical frequency combsystem and to gain a deep system understanding.
The scope of this PhD work will include the development of a prototype laser and customized control system as well as the development of frequency stabilisation systems with focus on dedicated space application such as optical atomic clocks and LIDAR systems.
The main topics are:
Prototype development of an FPGA-based instrument control unit with a commercial rapid prototyping FPGA system in VHDL.
The development and optimisation of optical and electrical feedback units and interfaces.
Detailed modelling of the laser and stabilisation units, instrument feedback and control units,
including its correlation with respect to the various parameters under closed-loop control with the goal to reach an optimised MIMO DSP system architecture.
Closely supported by experts on laser stabilisation and FPGA development.
You will therefore take care of:
Setting up the control units and FPGA development system.
Setting up the laser system.
Development and setup of the laser control and detection units.
Performance modelling and out-of-loop performance verification at all interfaces to reach an overall system performance model.
Performance modelling of closed-loop effects, random opto-mechanical noise, and optical effects.
Coordination of interfaces to a parallel running project in order to target a future mission application.
Implementation and optimisation following state-of-the-art approaches or new innovative methods.
Prepare your results and progress to present in internal and external progress meetings, publications and conferences.
Educated to Master Degree Level (or equivalent) in Digital Signal Processing, Control Engineering, Electrical Engineering, Physics or related fields.
Experience with analogue and digital feedback loop development and implementation in VHDL.
Record of successful hardware and software development with the use of an FPGA system.
Ideally background and interest in short-pulsed laser systems and fibre optics.
Broad interest in hands-on system development in a laboratory environment (electronics, photonics, mechanics, etc.).
Experience with programming, including C/C++, MATLAB or python.
Very high level of self-motivation and determination.
Good communication, organization, collaboration and time management skills.
Open-minded and willingness to discover and drive new research topics.
Fluent in English. German would be a plus
