Discrete Beam Combiner
The interferometry activity of the Astrophotonics group addresses the development of three-dimensional integrated-optics beam combiners for infrared stellar interferometry.
Optical Frequency Combs
Optical frequency combs (OFC) are light sources consisting of a regular array of narrow spectral lines.
AO-assisted Astrophotonics
Atmospheric turbulence is the main limiting factor for the achievement of high-resolution images with single aperture, ground based telescopes.
Arrayed Waveguide Grating and Echelle Gratings
Integrated spectrometers on the basis of AWGs and photonic Echelle gratings are important instruments for airborne and spaceborne spectroscopic surveys.
Fibre Bragg Gratings
Low-mass stars and brown dwarfs emit a substantial fraction of their light at NIR wavelengths and NIR spectroscopy is the most efficient way to study these objects.
