Soliton molecules possess abundant degrees of freedom, therefore exhibiting the versatile dynamics. The manipulation of soliton molecules has been vigorously ongoing in recent years, with the aim of achieving on-demand harnessing. In our work, via selecting two different states of the soliton pair as encoding elements, a binary encoding scheme is experimentally realized. The proposed scheme verifies the feasibility of solitonic encoding by gain control, as well as releases its potential in all-optical storage.

Artificial manipulations on dissipative soliton molecules stimulate the exploration for controllable temporal and internal assemblies. Phase-defined four regions are implemented to constitute the high-distinguishable quaternary encoding format and realizes the all-optical storage.

This paper introduces the concept of the Solitonic Internet, an engineering-focused alternative to quantum networking. By encoding information in phase-locked solitonic bursts transmitted through optical fiber or microwave links, the system achieves dispersion-free transport, resilience against noise, and room-temperature operation. The paper formulates an operational model based on the nonlinear Schrödinger equation, defines coherence and fidelity metrics, and presents simulated results comparing detection probability versus SNR for conventional and solitonic approaches. Security analysis highlights the robustness of soliton-based signaling against eavesdropping and jamming, while infrastructure compatibility ensures feasibility with existing telecom networks. The Solitonic Internet provides a practical pathway toward secure, long-distance communication without the complexity of quantum repeaters or cryogenic systems.
