Research engineer in optics, photonics, physics
Typical job : Expert in experimental development
Contract duration: 12 months
Start of contract: March 2020
Desirable area of expertise: optics, photonics, lasers, general physics
Diploma or university title: Engineer diploma or PhD in Physics
The engineer will ensure the design and implementation of the laboratory's instrumental projects in the fields of photonics and optical systems. He / she participates in the scientific projects of the laboratory related to the development, tuning, operation and applications of fiber and free space optical systems, near infrared lasers, semiconductor sensors and their associated electronics
Context and work environment
The ARTEMIS laboratory is a joint research unit of CNRS, Côte d´Azur University (UCA) and Côte d'Azur Observatory (OCA). Its main scientific theme is the physics and the detection of gravitational waves (GW).
In this context, researchers, engineers and laboratory technicians are deeply involved in the science and construction of detectors intended for the detection of GW. Several experimental projects are at the heart of the laboratory's instrumental activities: Virgo and Einstein Telescope terrestrial detectors, as well as the future LISA space observatory.
The ARTEMIS laboratory and its researchers were pioneers in the development of the Franco-Italian Virgo detector, in particular they had major contributions in the development of the laser system. The Virgo detector, with the American double LIGO detector, has already revealed several observations of gravitational waves.
Mission of the European Space Agency, LISA (Laser Interferometer Space Antenna) will allow a considerable extension of the observation of the Universe through GWs. It will use laser interferometry, already exploited by LIGO and Virgo terrestrial detectors, but in space, and in a frequency band beyond the reach of terrestrial detectors: https://www.lisamission.org/articles/lisa-mission/lisa-mission-gravitati...
The precision targeted for the phase measurement of the heterodyne interferometer in the LISA instrument implies a particularly detailed study of the sources of noise and systematic effects, and will make, of the phase of AIVT (Assembly, Integration, Validation and Test) in which France is involved, a particularly important step.
In this context, the engineer will participate in the development of the laboratory's instrumental projects around the AIVT activities of the LISA instrument. In particular, he/she will bring his/her contribution to the high precision metrology of optoelectronic devices called photoreceivers (PRs), devices intended for the detection of optical interference signals and their transformation into amplified electrical signals. He/she will also support other laboratory projects, in particular the design, the realization of prototypes and the characterization of complex optical equipment for ground tests, intended on one side for the scattered light studies and to another side for the measurement of opto-mechanical coupling, phenomena inherent in the optical benches of the LISA experiment.
