Tunable Lightsource With Cascading Phase-Shifting Filtering
Tunable lasers or wavelength swept light sources are used in a wide range of applications like profilometry, laser spectroscopy, optical sensors for measuring pressure and temperature and optical coherence tomography. A powerful concept enabling ultra-high tuning rates is e.g. Fourier Domain Locking (FDML).
FDML lasers, however, use kilometre long glass fibres which results in high production costs for these lasers and damping of the light for higher frequencies. The presented tunable light source does not use a glass fibre which enables the production of tunable light sources down to 600nm, whereas tunable FDML lasers are limited above ~1000nm. Speeds up to 340 000 wavelength sweeps per second over ~100nm at 0.1nm linewidth have been reached with the available prototype.
