Quantum Maxwell-Bloch equations for spatially inhomogeneous semiconductor lasers
Holger F. Hofmann, O. Hess
We present quantum Maxwell-Bloch equations (QMBE) for spatially inhomogeneous semiconductor laser devices. The QMBE are derived from fully quantum mechanical operator dynamics desc…
Spatial holeburning effects in the amplified spontaneous emission spectra of the non-lasing supermode in semiconductor laser arrays
Holger F. Hofmann, Ortwin Hess
The amplified spontaneous emission spectrum of the light field in the non-lasing supermode of two coupled semiconductor lasers is analyzed using linearized Langevin equations. It i…
Spontaneous emission spectrum of the non-lasing supermodes in semiconductor laser arrays
Holger F. Hofmann, Ortwin Hess
It is shown that the interference between spontaneous emission into the non-lasing supermode and the laser field of a semiconductor laser array causes spatial holeburning which cou…
Polarization fluctuations in vertical cavity surface emitting lasers: a key to the mechanism behind polarization stability
Holger F. Hofmann, Ortwin Hess
We investigate the effects of the electron-hole spin dynamics on the polarization fluctuations in the light emitted from a vertical cavity surface emitting laser (VCSEL). The Lange…
The split density model: a unified description of polarization and array dynamics for vertical cavity surface emitting lasers
Holger F. Hofmann, Ortwin Hess
A rate equation model describing the laser dynamics of general one or two dimensional vertical cavity surface emitting laser (vcsel) arrays is introduced. It is shown that the theo…
