Laboratory

Professor Razzari’s laboratory at INRS-EMT hosts state-of-the-art equipment for the design and numerical simulation of photonic devices, as well as for their optical characterization. In particular, nanophotonic components and metasurfaces are investigated, for their ability to tailor radiation-matter interactions overcoming the limits commonly imposed by natural materials.

Equipment

- Advanced simulation software (COMSOL Multiphysics and CST MWS) associated with computer workstations for the design and simulation of photonic devices

- Amplified femtosecond Yb:KGW laser source (Light Conversion, PHAROS: 1030 nm, 170 fs, max. 1 mJ, 6 W) coupled to an optical parametric amplifier (Light Conversion, ORPHEUS: wavelength tuning range: 1.3 - 16 um)

- Fourier-transform infrared spectrometer (Bruker, VERTEX70: frequency range; 400 - 8000 cm-1)

- Fourier-transform terahertz spectrometer (Blue Sky Spectroscopy, customized, vacuum required: frequency range: 50 - 400 cm-1)

- Antenna-based terahertz time-domain spectroscopy TDS systems (TeTechS - free space setup, and Menlo - fiber based setup). In addition, the ytterbium femtosecond laser is also used to pump a variety of in-house built TDS systems (featuring, e.g., high peak electric field or ultrabroad operation bandwidth). These include a custom-built fast imaging system with time-domain and hyperspectral capabilities

- General tools for the characterization of optical / optoelectronic components
