Intensity fluctuations correlation for a Fabry Perot semiconductor laser: A semiclassical analysis
نویسندگان
چکیده
The correlation between the amplitude fluctuations of two laser beams emitted by a semiconductor laser is calculated using a semiclassical laser model including vacuum fluctuations present at the laser facets as well as phenomena such as spatial hole burning and gain suppression. A thorough analysis shows strong influence of the laser structure and parameters. We concentrate on the case of Fabry Perot lasers where we demonstrate that a direct connection between amplitude noise and the correlations exists. A detailed analysis shows the influence of internal loss, gain suppression and spatial hole burning. Finally, a direct comparison with obtained experimental results is performed. q 1998 Elsevier Science B.V.

Amplitude squeezing with a Fabry-Perot semiconductor laser: existence of an optimum biasing condition.
The effect of gain suppression on amplitude squeezing with a Fabry-Perot semiconductor laser is studied with a semiclassical model. A strong decrease of the internal amplitude noise and an optimum biasing point with minimum amplitude noise are demonstrated. Small gain nonlinearities improve external compression.

We show a unique dual-wavelength external-cavity laser diode with frequency tracking capability and obtain a stable beat frequency between the dual-wavelength output. By using a Fabry–Perot interferometer as the frequency discriminator and the time-gating technique in a servo loop, the peak-to-peak frequency fluctuations were stabilized, with respect to the Fabry–Perot cavity, to 86 kHz in the ...
متن کاملGeneration of amplitude-squeezed light from a room-temperature Fabry-Perot semiconductor laser.
Amplitude-squeezed light with intensity f luctuations 29% below the standard quantum limit (SQL) is produced from a pump-suppressed room-temperature semiconductor laser, corresponding to 41% below the SQL after correction for detection eff iciency. Excess noise, which degrades the observed squeezing, appears to be associated with the presence of weak longitudinal side modes. PACS numbers: 42.50...
