Brillouin fiber ring lasers have already been extensively studied [1] and results have shown that the generated first order Stokes wave has less intensity and phase noise than the seeded pump. This increase in coherence is attractive for many sensing applications, whether in the field of fiber sensors or remote sensing systems such as LIDAR. Brillouin fiber lasers with several Stokes components can...
We detail an innovative laser device based on a new relaxation mechanism for confined exciton-polaritons which preserves nonlinearity. We demonstrate the selective activation of polariton lasers at different wavelengths allowing to perform all-optical logic operations with fully coherent output [1].
Coherent excitation of a microcavity resonance leading to enhanced nonlinear interaction is experimentally demonstrated for the first time. A tailored chirped pulse maintains the cavity enhancement effect, despite the resonance nonlinear frequency shift.
We report on the observation of a compact optical microwave source based on a whispering gallery mode (WGM) laser. The use of a single 160-??m diameter erbium-doped glass microsphere and two half fiber tapers allows a dual single-mode laser emission around 1550 nm to be obtained. The generated beat note at 10.86 GHz has a linewidth of 22 kHz. This preliminary experimental demonstration shows the potentialities...
We present results on the realization of a dual wavelength micro-spherical glass laser source fabricated from the Erbium doped fluoride glass ZBLALiP. The pump wavelength (1480 nm) is close to that of the laser field (~1550 nm) and we use a half taper to couple both fields in and out the micro-spherical laser. The coupling by two half tapers on the same micro-spherical resonator allows two single...
