mirSense (MirS), France

Mario De Paz Diez — 2021-09-15T12:59:03Z

mirSense is a French SME composed of 9 permanent employees and 3 PhD students. mirSense is a startup which develops and produces QCL diodes and advanced photonic devices such as wideband tunable sources for real-time, high sensitivity trace detection and chemical analysis of gas, liquids and solids by infra-red laser absorption spectroscopy, as well as high power lasers for DIRCM applications. mirSense is a spin-off from the III-V Lab in France where mid infrared sources based on Quantum Cascade Lasers have been developed during fifteen years. Thanks to this research, mirSense, established at the beginning of 2015, has a “unique” approach, using only microelectronic solutions without any moving mechanical or optic components, resulting in compact and robust devices. mirSense's expertise is the development a unique silicon platform that enables mid-range photonics ICs. We use it for combining lasers and providing advanced MIR sensing solutions. Our philosophy is to be as close to the applications as possible. Our target customers are equipment manufacturers needing sensing systems such as for gas, chemical or medical sensing. Examples of mirSense products are : a multigas detecting laser module with pulsed or CW operation at room temperature, with 10 mW mean power, which offers a 100 cm-1 tuning range and a single gas laser, which can deliver more than 100 mW. We have already delivered hundreds of these lasers to customers.

Within the consortium, mirSense will realise dual wavelength MIR QCLs combined with a MOPA geometry. This will permit high power MIR QCLs to pump new MIR TMDs for efficient FIR generation. mirSense will further evaluate the new sources in terms of performances and their integration in compact spectrometers.

University of Leeds (ULEEDS), UK

Yann Colin — 2015-12-07T16:37:34Z

The University of Leeds is one of the top ten universities for research and student education in the UK and is internationally acknowledged as a centre of excellence for a comprehensive range of academic and professional disciplines. It has an annual income of over €800M and over 38,000 students (of which 10,000 are post graduates) and over 8,700 staff from more than 100 different countries. Its annual research income exceeds €240M of which approximately 10% derives from EU awards.

The School of Electronic and Electrical Engineering has a long-standing history of pre-eminence in high frequency electronics, incorporating fundamental understanding, design, modelling, and fabrication of devices, components, and subsystems. The School was ranked in the top 5 in the UK for electronic engineering research in the most recent UK Government Research Excellence Framework, with 100% of activity deemed ‘internationally excellent' or ‘world-leading'.

The School of Physics has a world leading reputation in the theory, fabrication, characterisation and study of metallic thin films and magnetic materials. The School is in the top 5 in the UK for research impact according to the most recent UK Government Research Excellence Framework. Both the schools form part of the Bragg Centre, the flagship materials research centre of the University of Leeds. The centre benefits from a recent €108M investment by the University.

Within the consortium, ULEEDS will provide state-of-the-art material growth by molecular beam epitaxy, of both high power GaAs-AlGaAs THz QCLs for pumping 2D materials and high quality Bi2Se3 and (BiSb)2Te3 films. TI devices, QCL devices and integrated QCL-TI devices will be fabricated in the ULEEDS nanotechnology cleanroom. Linear and non-linear THz spectroscopy of TI materials will be carried out in the ULEEDS THz laboratory.

École Polytechnique Fédérale de Lausanne (EPFL), Switzerland

Yann Colin — 2015-12-07T16:37:30Z

EPFL is one of two federal technical universities in Switzerland. It has three missions : education, research and technology transfer at the highest international level. EPFL, in its location on the shores of Lake Geneva, brings together a campus of more than 10,000 people with more than 250 laboratories and research groups. With 120 nationalities represented on campus and more than 50% of the professors coming from abroad, the School is one of the world's most cosmopolitan universities. The EPFL School of Engineering (STI) consists of more than 50 laboratories organized within 5 institutes at the intersection of mechanics, electrical engineering, micro-technology, and materials science. The research projects conducted in the STI often lead to tangible applications in areas as diverse as biomedical sciences ; energy technology ; the treatment and transmission of information ; microelectronics and micro-systems ; novel materials ; robotics and other mechanical systems. A key resource of EPFL is the CMI – a state of the art 100-mm user nanofabrication facility which enables material growth, advanced etching and nanofabrication.

EPFL will be growing high quality 2D materials using CVD and MOCVD, transferring them on QCL and other structures and providing expertise on 2D device manufacturing, optical and electrical characterization.

Terahertz Physics Group at Bielefeld University (UNIBI), Germany

Yann Colin — 2015-12-07T16:37:08Z

As a strong research university with international appeal and innovative teaching concepts, Bielefeld University makes an important contribution to a progressive and participatory knowledge society. It is an attractive, family-friendly place to work and study, characterized by an open culture of communication, interdisciplinarity, diversity and freedom of personal development.

UNIBI was founded in 1969 with an explicit research assignment and a mission to provide high-quality research-oriented teaching. With 25,000 students, it now comprises 13 faculties covering a wide range of subjects in the arts and humanities, natural sciences, and technology. In addition, a medical faculty is currently in the process of being established.

UNIBI regards itself as a strong research university, ranked in the top 25 percent of the national competitive field. Its research profile is based on four strategic, thematic research priorities, which are linked by three cross-cutting topics. All research priorities are interdisciplinary and involve various faculties and central scientific institutions. Cutting-edge interdisciplinary research is carried out on the highest international level, in particular within the framework of systematically selected third-party funded projects. The strategic research priorities focus on innovative basic research. They provide important focal points for possible transfers of academic research into industrial and societal applications, in line with UNIBI's official motto “Transcending Boundaries”.

Within the consortium, as well as coordinating the project, the UNIBI group will provide :

1) THz spectroscopy in many different modalities (standard THz TDS in the range 0.1 - 4.5 THz, ultrabroadband spectroscopy using THz air-photonics in the range 1 - 30 THz, nonlinear THz spectroscopy with THz fields up to at least 300 kV/cm, optical pump - THz probe, THz pump - optical probe, THz pump - THz probe) in order to understand the ground state conductivity, carrier dynamics, and nonlinear response of active materials used within the project, as well as the structures based thereon.

2) Modelling of nonlinear response of Dirac materials using the home-developed thermodynamic model, which was successfully employed to understand and describe nonlinear conductivity, saturable absorption, and HHG in graphene.

3) Feedback to other members of the consortium regarding material, structure, and device optimization.
