Multiwavelength Optical micRosourcEs on silicon for Mid-InfraRed integrated sensing – MOREMIR

The aim of this project is to develop a CMOS compatible integrated photonic platform for applications in the mid infrared (MIR, wavelength range between 2 and 20 µm). This wavelength domain is of great interest for a huge range of applications such as medical and environment sensors, security, defence and astronomy, which require compact and low cost devices.
To achieve this vision we will i) adopt a strategy that has been highly successful in creating compact near infrared (NIR) photonic components integrated onto a silicon chip for optical interconnects and telecom applications and ii) adapt this strategy to MIR wavelengths where specific and significant research efforts in materials, devices, integration technologies and photonic designs are required.
More specifically in this project we aim at building a multiwavelength source, based on III-V on silicon heterogeneous integration scheme, operating in the 2-5µm wavelength range. For that purpose, two kinds of laser sources, namely antimony based microlasers and InP based Quantum Cascade Lasers (QCLs), will be integrated with a silicon photonic circuit. These devices will represent a critical building block for future MIR sensing technologies.
