Wave-mixing analysis for THz-signals generation in dc-biased semiconductor optical devices at room temperature [PDF]
, 2010 Wave-mixing at 370-GHz in a SOA and FP semiconductor laser is investigated by using a FROG-system. A comparison of the optical time-fluctuations measured at their output stresses the importance of a resonant cavity in THz-signals generation from ...

Bifurcation analysis of a semiconductor laser with filtered optical feedback
, 2006 We study the dynamics and bifurcations of a semiconductor laser with delayed filtered feedback, where a part of the output of the laser re-enters after spectral filtering.

Dynamics of Multisection Semiconductor Lasers
Journal of Mathematical Sciences, 2004 We investigate the longitudinal dynamics of multisection semiconductor lasers based on a model, where a hyperbolic system of partial differential equations is nonlinearly coupled with a system of ordinary differential equations. We present analytic results for that system: global existence and uniqueness of the initial‐boundary value problem, and ...
