Journal ArticleDOI
Offset phase locking of Er,Yb:glass laser eigenstates for RF photonics applications
Mehdi Alouini,B. Benazet,Marc Vallet,Marc Brunel,P. Di Bin,Fabien Bretenaker,A. Le Floch,Philippe Thony +7 more
TL;DR: In this article, an optical source of microwaves with very low phase noise for communications and radar systems is realized and tested by dual-frequency operation of a diode pumped Er,Yb:glass laser.
Journal ArticleDOI
Long-range polarimetric imaging through fog
Julien Fade,Swapnesh Panigrahi,Anthony Carré,Ludovic Frein,Cyril Hamel,Fabien Bretenaker,Hema Ramachandran,Mehdi Alouini +7 more
TL;DR: With the limited-dynamics detector used, a maximum fourfold increase in contrast was demonstrated under bright background illumination using polarimetric difference image, and the efficiency of using polarized light for source contrast increase with different signal representations was compared.
Journal ArticleDOI
Dual tunable wavelength Er,Yb:glass laser for terahertz beat frequency generation
TL;DR: In this article, a dual tunable wavelength operation of Er,Yb:phosphate glass laser is reported, where the spatial separation of the laser eigenstates and the use of two properly designed intracavity etalons permit one to tune the two wavelengths independently from 1540.5 to 1562.7 nm.
Journal ArticleDOI
Experimental demonstration of a tunable dual-frequency semiconductor laser free of relaxation oscillations
Ghaya Baili,Loic Morvan,Mehdi Alouini,Daniel Dolfi,Fabien Bretenaker,Isabelle Sagnes,Arnaud Garnache +6 more
TL;DR: Tunable dual-frequency oscillation is demonstrated in a vertical external-cavity surface-emitting laser and the class-A dynamics of this laser enables one to suppress the electrical phase noise in excess that is usually observed in the vicinity of the beat note.
Journal ArticleDOI
Experimental Investigation and Analytical Modeling of Excess Intensity Noise in Semiconductor Class-A Lasers
TL;DR: In this article, an analytical model is derived, based on multimode Langevin equations, to describe the observed laser excess noise over the whole bandwidth, and the measured levels of excess noise correspond to side mode suppression ratios (SMSRs) ranging from 70 to 90 dB.
