Coexistence of thermal noise and squeezing in the intensity fluctuations of small laser diodes

open access: yes, 2000
The intensity fluctuations of laser light are derived from photon number rate equations. In the limit of short times, the photon statistics for small laser devices such as typical semiconductor laser diodes show thermal characteristics even above ...
