Implementation of optical feedback interferometry for sensing applications in fluidic systems [PDF]

, 2016
Optical feedback interferometry is a sensing technique with relative recent implementation for the interrogation of fluidic systems. The sensing principle is based on the perturbation of the laser emission parameters induced by the reinjection in the ...

Phase Relationship of Photodetected Signals of an Optical Feedback Interferometry Sensor

, 2015
International audienceOptical Feedback Interferometry signals can be acquired by photodetection either from rear or front facet of the laser. We present a model that links both signals to the injection current.

Laser feedback interferometry with THz QCLs: a new technology for imaging and materials analysis

, 2016
Considerable interest exists for sensing and imaging technologies in the terahertz (THz) spectral range, in particular for the interrogation of materials of an organic or biological nature. Development in THz quantum cascade lasers is seeing higher operating temperatures and peak output powers in pulsed mode, accentuating their place as the preferred ...
