Overview

Demonstrates a novel technique for creating flexible optical materials, suggesting new applications in flexible devices.

Key Points

  • To develop flexible optical materials that overcome the rigidity limitations of traditional crystals.
  • Utilized corrosion-assisted patterned stripping (CAPS) to fabricate flexible Er:YAG filaments from bulk crystals.
  • Tested mechanical compliance by stretching the filaments up to 300% and assessing recovery after stretching cycles.
  • Integrated filaments onto elastomeric substrates to evaluate low-loss light transmission during deformation.
  • Filaments displayed remarkable mechanical compliance with full recovery after thousands of stretching cycles.
  • Demonstrated stable light transmission in integrated flexible optical waveguides even during deformation.
  • Achieved a net gain of 10 dB in a flexible optical waveguide amplifier, comparable to rigid systems.
