Experimental observations of multi-mode dynamics in an external cavity semiconductor laser
نویسندگان
چکیده
We present experimental results of the dynamics in a semiconductor laser operating on several longitudinal modes subject to external feedback. Both low-frequency fluctuations (LFFs) and locked states are studied through observing the outputs from the dominant mode, all modes except the dominant mode, and all modes. Synchronized dropout events of LFFs are observed among each of the solitary modes while energy competition and trading occurs among these modes when the total output exhibits the locked state.

Theoretical comparison analysis of long and short external cavity semiconductor laser
In this paper, considering optical feedback as an optical injection, and taking in to account round-trip time role in the external cavity, a standard small signal analysis is applied on laser rate equations. By considering the relaxation oscillation (f2) and external cavity frequencies (f) ratio for semiconductor laser, field amplitude response gain, optical phase and carrier number for long ex...

In this paper, by placing the electro optical modulator (EOM) into the external cavity of the semiconductor laser (SL) and amplitude modulation of the optical feedback, the dynamical variation of the output intensity of the laser has been studied. This is analyzed numerically via bifurcation and time series diagrams with respect to the applied amplitude modulation index, and modulation voltage...
متن کاملUsing of Broadened Asymmetric Waveguide Structure for 980nm Diode Laser
Laser diode beam divergence is the main parameter for beam shaping and fiber optic coupling. Increasing the waveguide layer thickness is the conventional method to decrease the beam divergence. In this paper, the broadened asymmetric waveguide is introduced to decrease the divergence without increasing the optical power. The asymmetric waveguide was used to shift the vertical optical field to n...
متن کاملDynamical regimes of multi-stripe laser array with external off-axis feedback
We study theoretically the dynamics of a multistripe laser array with an external cavity formed by either a single or two off-axis feedback mirrors, which allow to select a single lateral mode with transversely modulated intensity distribution. We derive and analyze a reduced model of such an array based on a set of delay differential equations taking into account transverse carrier grating in ...
متن کاملSynchronization and multi-mode dynamics of mutually coupled semiconductor lasers
Dynamics of coupled semiconductor lasers is investigated by numerical simulations. A realistic laser simulation engine is used to study the synchronization and dynamical regime in two mutually coupled Fabry-Perot and/or DFB lasers. Both, singleand multi-mode operation regimes are studied with emphasis on the role of the multiple laser-cavity modes. Our findings indicate that the two laser synch...
