研究目的
Investigating the formation of optical supramolecular structures in a fibre laser by tailoring long-range soliton interactions.
研究成果
The study demonstrates the formation of stable, highly-ordered supramolecular structures of optical solitons in a fibre laser cavity through tailored long-range interactions. These structures exhibit potential applications in optical information storage and ultrafast laser-field manipulation. The ability to control long-range interactions opens new avenues for studying complex soliton molecules and optically simulating many-body systems.
研究不足
The study is limited by the bandwidth of the oscilloscope, which restricts the resolution of temporal features. Additionally, the exact number of solitons in the supramolecular structure varies randomly, and independent control of individual solitons has not been demonstrated.
1：Experimental Design and Method Selection:
The study involves a mode-locked fibre laser with a pulse repetition rate locked to an acoustic resonance in a photonic crystal fibre (PCF) core. The cavity has net anomalous dispersion, ensuring operation in the soliton regime.
2：Sample Selection and Data Sources:
The experiments were carried out using a 2-m-long solid-core silica photonic crystal fibre (PCF) with a GHz-rate acoustic core resonance inserted into the laser cavity.
3：List of Experimental Equipment and Materials:
The setup includes a 30-GHz photodetector, a 33-GHz oscilloscope, a second-harmonic autocorrelator, an optical spectrum analyser, and several-km-long SMF-28 fibre for time-stretched dispersive Fourier transformation (TS-DFT).
4：Experimental Procedures and Operational Workflow:
The laser pump power and intra-cavity attenuator were adjusted to enable self-assembly of a supramolecular structure. The soliton supramolecule's fine structure was monitored over time.
5：Data Analysis Methods:
The timing jitter and soliton spacing were measured using the oscilloscope in persistence-mode. The optical spectrum and soliton duration were measured using an optical spectrum analyser and a second-harmonic autocorrelator, respectively.
