Tailoring the profile and interactions of optical localized structures

Area of Science:

• Nonlinear optics
• Optical physics
• Condensed matter theory

Background:

• Optical localized structures (LS) are key phenomena in nonlinear optics.
• Understanding and controlling LS interactions is crucial for applications in optical computing and data storage.
• Nonlinear interferometers provide a platform for studying complex optical phenomena.

Purpose of the Study:

• To experimentally demonstrate the broad tunability of optical localized structures (LS) in a nonlinear interferometer.
• To investigate the relationship between system spatial frequency bandwidth and LS characteristics.
• To show how modifying LS tails can tune interactions between LS pairs and their bound states.

Main Methods:

• Experimental demonstration in a nonlinear interferometer.
• Analysis of LS dependence on spatial frequency bandwidth.
• Modification of LS tails to influence inter-LS interactions.

Main Results:

• Broad tunability of main features of optical localized structures (LS) was experimentally achieved.
• Modification of LS tails was shown to tune interactions between LS pairs.
• Equilibrium distances for LS bound states were successfully tuned.

Conclusions:

• The study confirms that LS features in nonlinear interferometers are broadly tunable.
• Tuning LS tail properties offers a method to control inter-LS interactions and bound state formation.
• Experimental findings align with a general theoretical model for LS in nonlinear dissipative systems.
