Objectives and tasks l.jpg
Objectives and Tasks

  • Context: Optical Communications using Chaotic Waveforms.

  • Linked to OCCULT & PICASSO Projects

  • General Objective: Study the dynamics of robust and compact devices which can allow to increase the level of security and the use of new encoding techniques.

  • Specific Tasks (already running / to be tackled)

  • Study of edge-emitting semiconductor lasers subject to several feedback loops or subject to a state dependent feedback.

  • Study of semiconductor lasers with two or three integrated sections. Modulation in the feedback-phase of one of the sections. Nonlinear feedback.

  • Chaos generation in electro-optical systems. Systems with several delays or with variable delay.

  • Exploration of the chaotic regimes in semiconductor ring lasers.Synchronization and message encoding/decoding.

  • Spatio-temporal chaos in broad area devices subject to optical feedback. Synchronization. Codification techniques.
