Dynamic Crystal Photonics: Mechanically Mobile Organic Nonlinear Optical Microring Resonators.

Area of Science:

• Photonics
• Materials Science
• Nanotechnology

Background:

• Organic crystal microring resonators (MRRs) are key components in photonic devices.
• Controlling the mechanical motion and photonic behavior of MRRs is crucial for advanced applications.
• Current methods often lack the dexterity for complex 3D manipulation.

Purpose of the Study:

• To investigate the photonic properties of organic crystal MRRs under dynamic mechanical manipulation.
• To introduce the concept of dynamic crystal photonics.
• To demonstrate 3D spatial control over MRR behavior.

Main Methods:

• Fabrication of MRRs via surface-tension-assisted self-assembly of 6,6'-((1E,1'E)-hydrazine-1,2-diylidenebis(methaneylylidene))bis(2,4-dibromophenol) (HDBP).
• Micromechanical reconfiguration of MRRs into various architectures using an atomic force microscopy cantilever tip.
• Characterization of photonic traits, including nonlinear optical emission and whispering-gallery modes, during mechanical motion.

Main Results:

• MRRs exhibited nonlinear optical emission and frequency comb-type whispering-gallery modes.
• MRRs were successfully reconfigured into diverse strained architectures (lifting, transferring, standing, spinning, rolling).
• Photonic properties were retained throughout dynamic mechanical motions, demonstrating mechanical robustness and enabling 3D spatial control.

Conclusions:

• Dynamic crystal photonics is a viable concept for controlling soft organic elements.
• The demonstrated 3D manipulation capabilities pave the way for next-generation mechanophotonic systems.
• Precise control over spatial orientation and photonic behavior of organic MRRs is achievable.
