Summary
This study demonstrates near-perfect absorption in a single-polarization single-mode photonic crystal fiber (SPSM PCF) for long-wave infrared light. The design utilizes epsilon-near-zero materials for sensitive environmental monitoring applications.
Area of Science:
- Photonics
- Optical Materials
- Nanophotonics
Background:
- Photonic crystal fibers (PCFs) offer unique light manipulation capabilities.
- Achieving single-polarization single-mode (SPSM) operation is crucial for advanced optical devices.
- Materials with epsilon-near-zero (ENZ) and epsilon-negative (ENG) properties are key for resonant phenomena.
Purpose of the Study:
- To design and demonstrate a novel SPSM PCF for near-perfect resonant absorption in the long-wave infrared (LWIR) spectrum.
- To investigate the underlying plasmonic resonance mechanism within the PCF.
- To explore the potential of the PCF as a sensitive spectrometer for environmental monitoring.
Main Methods:
- A triangular lattice PCF design with circular air holes and rectangular slots in the core was employed.
- Silicon carbide (SiC) was partially filled into specific air holes to induce ENZ and ENG properties.
- The overlap of optical modes with lossy ENG rings was optimized to achieve SPSM operation and strong plasmonic resonance.
Main Results:
- Near-perfect resonant absorption was achieved in the LWIR range (10–11 μm).
- The SPSM behavior was realized by carefully controlling mode overlap with the SiC-filled rings.
- A strong plasmonic resonance was confirmed through adjustments to the core-shell structure radii.
Conclusions:
- The developed plasmonic-based PCF structure effectively achieves single-polarization single-mode operation with near-perfect absorption.
- The resonance wavelength can be tuned by altering the material properties within the PCF air holes.
- The PCF shows significant promise as a highly sensitive, short-length spectrometer for environmental sensing.
