چکیده
We propose a simple method to generate broadband polarization chaos using two mutually coupled free-running vertical-cavity surface-emitting lasers (VCSELs). Specifically, we quantitatively investigate the effect of critical external parameters (bias current, frequency detuning and coupling coefficient) on bandwidth in scenarios parallel injection orthogonal injection, reveal physical mechanism enhancement scenarios. Final simulation results show that chaotic signals obtained from can reach 35.15 GHz 32.96 GHz, respectively.

Impact of light polarization on chaos synchronization of mutually coupled VCSELs.
We demonstrate that dynamical polarization switching in mutually coupled vertical-cavity surface-emitting lasers (VCSELs) has a profound impact on the chaotic dynamics in the system drastically improving the in-phase (anti-phase) synchronization between the modes of the two VCSELs with the same (orthogonal) polarizations. Furthermore, an exchange of the leader-laggard role is observed with the ...
متن کاملGeneration of 20 GHz, sub-40 fs pulses at 960 nm via repetition-rate multiplication.
Optical filtering of a stabilized 1 GHz optical frequency comb produces a 20 GHz comb with approximately 40 nm bandwidth (FWHM) at 960 nm. Use of a low-finesse Fabry-Pérot cavity in a double-pass configuration provides a broad cavity coupling bandwidth (Deltalambda/lambda approximately 10%) and large suppression (50 dB) of unwanted modes. Pulse durations shorter than 40 fs with less than 2% res...
متن کاملPolarization Division Multiplexed Data Transmisison Using Surface Grating VCSELs
In recent years, we have shown that an unprecedented level of polarization stability can be reached with surface gratings, which provide a monolithically integrated type of polarization-dependent feedback. Single-mode as well as multimode grating VCSELs have been fabricated in large quantity and have been shown to be polarization-stable with high orthogonal polarization suppression ratio not on...
متن کاملLeader-laggard relationship of chaos synchronization in mutually coupled vertical-cavity surface-emitting lasers with time delay.
We experimentally and numerically observe synchronization of chaos in two mutually coupled vertical-cavity surface-emitting lasers (VCSELs) with time delay. We observe in-phase and antiphase synchronization of polarization-resolved chaotic temporal wave forms under the condition of wavelength matching. We investigate leader-laggard relationship between two chaotic wave forms of mutually coupled...
متن کاملIntensity and polarization self-pulsations in VCSELs
We implement a dynamical model that describes the polarization behavior in VCSELs containing an absorbing region surrounding the active zone. We find four regions of qualitative different behaviors: stable linearly-polarized operation, intensity pulsations of a linearly-polarized component, pulsations of both total intensity and polarization components, and polarization self-pulsations with con...
