What are the Challenges in Frequency Conversion at the Nanoscale?
Despite its potential, there are several challenges in implementing frequency conversion at the nanoscale:
Material Limitations: Finding materials that exhibit strong non-linear properties at the nanoscale can be difficult. Fabrication Precision: Creating nanostructures with the required precision is challenging and often requires advanced fabrication techniques. Efficiency: The efficiency of frequency conversion processes can be low, requiring further optimization.
