Area of Science:

  • Photonics
  • Nanotechnology
  • Optical Engineering

Background:

  • Photonic crystals offer unique light manipulation properties.
  • Existing designs often face limitations in sensing and modulation capabilities.
  • Developing integrated optical devices requires efficient buffering and high sensitivity.

Purpose of the Study:

  • To introduce a novel irregular waveguide structure for enhanced optical buffering.
  • To investigate the sensing and modulation performance of the proposed structure.
  • To achieve high refractive index and electro-optical sensitivity.

Main Methods:

  • Modification of an elongated hexagonal photonic crystal (E-PhC) by replacing air holes with triangular gaps to form an irregular waveguide (EPCW).
  • Tuning triangle dimensions to optimize physical bit storage size.
  • Infiltration of microfluid with high refractive index into triangular gaps for sensing.
  • Application of external voltage to achieve dynamic modulation.

Main Results:

  • Achieved a minimal physical size for each stored bit of approximately 5.5510 μm.
  • Demonstrated high refractive index (RI) sensitivity of 379.87 nm/RIU due to microfluid infiltration.
  • Obtained high electro-optical (EO) sensitivity of 748.407 nm/RIU.
  • Attributed high sensitivity to strong optical confinement and enhanced light-matter interaction.

Conclusions:

  • The proposed irregular waveguide (EPCW) offers a paradigm for high buffering performance.
  • The structure exhibits excellent sensitivity for refractive index sensing and electro-optical modulation.
  • Enhanced light-matter interaction within the EPCW structure is key to its superior performance.
