By INESC Microssistemas e Nanotecnologias
The optoelectronics lab is equipped for optoelectronic and micromechanical device characterization: a 500 MHz scalar network analyzer, a 1 GHz spectral analyzer, a 2-phase 100 kHz lock-in amplifier and two 1-phase 100 kHz lock-in amplifiers. We have two picoammeters for low-speed, high sensitivity measurements. The lab also has a monochromator with reticles for 400-1600 nm optical measurements, a tungsten halogen and an arc-lamp light source. The lab has optical tables, a large assortment of power supplies and optical accessories. Measurements can be performed in vacuum or at controlled pressures. In the photonics lab we perform forward and inverse photonic design based on finite-difference time-domain and frequency-domain solvers to support the micro and nanofabrication of photonic devices, in particular, metasurfaces. The structured light laboratory enables device characterization (modal analysis decomposition of the shaped optical beams), comprising laser sources (visible and near-infrared), a reprogrammable spatial light modulator, cameras for beam detection, and a variety of optical and optomechanics components.
