What Are the Challenges in Developing Nanoscale Optical Resonators?
Despite their numerous advantages, developing nanoscale optical resonators comes with several challenges:
Fabrication Precision: Creating structures at the nanometer scale requires extremely high precision and control. Material Limitations: The choice of materials is often limited by their optical properties and compatibility with nanofabrication techniques. Loss Mechanisms: Minimizing losses due to absorption, scattering, and imperfect reflection is crucial for high-Q resonators. Integration: Integrating optical resonators with other nanoscale components and systems can be complex and challenging.
