Job offer: Design and Manufacturing Engineer for ultrafast optoelectronic components

Design and Manufacturing Engineer for ultrafast optoelectronic componentsThe THz Photonics team of the Institute of Electronics, Microelectronics and Nanotechnologies (IEMN) is looking to recruit a Design Engineer on a 12-month fixed-term contract. The objective of the work will be the design and fabrication of photodetectors for the generation of THz waves (100 GHz-10 THz).IEMN is a major player in the design and development of optoelectronic THz sources. The "THz Photonics" team has recently demonstrated the generation of THz waves by optoelectronic means with unequalled output power and efficiency. This source is based on the photodetection of a beat of two laser beams and requires the development of very high bandwidth semiconductor photodetectors.Within the framework of the Photowathz project financed by the Hauts de France region, the Photonique THz team aims to go even further in terms of power, spectral purity and tunability. To do this, new generation photodetectors, with distributed architecture optimized to operate with lasers of wavelength 1060 nm will be designed, manufactured and characterized. The stakes of this project are high, since it will demonstrate the feasibility of a THz source without equivalent today.The Engineer will be responsible for the design and manufacture of photomixers. To do so, he will:Design the photomixer using RF and photonic simulation software (CST, Lumerical, etc)To make the CAD of the lithography masksCarry out the steps in a clean room environment (resin coating, electronic/optical lithography, metallization, PVD deposits, plasma etching)Characterize the samples during the manufacturing process (AFM, profilometer, optical and electronic microscopy, electrical characterization)To carry out this mission, the engineer recruited will rely on the technological expertise of the team and all the personnel of the clean room.[1] F.
