Overview

Dynamic coherence control enhances optical imaging in compact systems, suggesting new avenues for photonic applications.

Key Points

  • The aim is to explore dynamic control of optical coherence using a liquid-crystal device to improve imaging and photonic computing.
  • Developed a dynamic nematic liquid-crystal device using Pancharatnam–Berry phase technology.
  • Utilized electro-optical reorientation for reversible coherence modulation.
  • Achieved programmable control through photopatterning with ultraviolet polarization.
  • Achieved 70% modulation efficiency in coherence control.
  • Demonstrated a response time of 20 ms for dynamic tuning.
  • Enabled speckle-free imaging and smart-window functionality in varying lighting conditions.
