Summary
Reducing the diameter of 3D printed light-emitting wires below the single-mode cutoff enhances emission directionality. This nanoscale approach effectively minimizes optical crosstalk in integrated photonic devices.
Area of Science:
- Photonics and optical engineering.
- Nanotechnology and materials science.
Background:
- Increasing integration density in photonic devices raises concerns about optical crosstalk.
- Minimizing signal interference is critical for advancing integrated optical components.
Purpose of the Study:
- To investigate the emission directionality of 3D printed light-emitting nano/microwires.
- To explore methods for mitigating optical crosstalk in high-density photonic integration.
Main Methods:
- Experimental measurements of emission directionality.
- Numerical simulations of light-emitting nano/microwires.
- Fabrication of 3D printed nanowires and microwires.
Main Results:
- Emission directionality significantly increases as wire diameter decreases below the single-mode cutoff.
- Nanoscale wires exhibit strong directionality, enabling effective crosstalk avoidance.
- Demonstrated successful reduction of optical crosstalk using diameter-controlled nanowires.
Conclusions:
- Controlling wire diameter is a viable strategy to enhance emission directionality and suppress crosstalk.
- 3D printed nanoscale light-emitting wires offer a promising solution for high-density photonic integration.
- The findings have implications for optical communication, sensing, and imaging applications.
