Square-wave switching in vertical-cavity surface-emitting lasers with polarization-rotated optical feedback: Experiments and simulations
(2012-09-12)
Article.
Accés obert
Article.
Accés obert
We study experimentally the dynamics of vertical-cavity surface-emitting lasers (VCSELs) with polarization-rotated (PR) optical feedback, such that the natural lasing polarization of a VCSEL is rotated by 90 deg and then ...

Square-wave switching of the intensities of the orthogonal linearly polarized components of the output of a vertical-cavity surface-emitting laser(VCSEL) found previously in experiments with polarization-changing optical ...
Extreme intensity pulses in a semiconductor laser with a short external cavity
(2013-06)
Article.
Accés obert
Article.
Accés obert
We present a numerical study of the pulses displayed by a semiconductor laser with optical feedback in the short-cavity regime, such that the external cavity round-trip time is shorter than the laser relaxation oscillation ...
Quantifying the synchronization of the spikes emitted by coupled lasers
(Institute of Physics (IOP), 2023-07-01)
Article.
Accés obert
Article.
Accés obert
Synchronization phenomena is ubiquitous in nature, and in spite of having been studied for decades, it still attracts a lot of attention as is still challenging to detect and quantify, directly from the analysis of noisy ...
Control and enhancement of beam quality of broadarea semiconductor devices and arrays by multimode interference couplers and two-dimensional gain modulation
(Institute of Electrical and Electronics Engineers (IEEE), 2013)

Dynamics of a semiconductor laser with feedback and modulation: experiments and model comparison
(Optical Society of American (OSA), 2022-03-14)
Article.
Accés obert
Article.
Accés obert
We study experimentally and numerically the dynamics of a semiconductor laser near threshold, subject to optical feedback and sinusoidal current modulation. The laser operates in the low frequency fluctuation (LFF) regime ...

Article.
Accés restringit per política de l'editorial
We present an experimental study of the effect of continuous-wave optical injection (OI) from a vertical-cavity surface-emitting laser (VCSEL) on the timing jitter of a gain-switched discrete-mode semiconductor laser (DML). ...
