What are the Applications of FWM in Nanotechnology?
FWM has several applications in nanotechnology, including:
Wavelength Conversion: FWM can convert an input wavelength to a different output wavelength, which is useful in Wavelength Division Multiplexing (WDM) systems for data transmission. Signal Regeneration: FWM can regenerate optical signals by reducing noise and improving signal quality, which is critical for long-distance communication. Quantum Information Processing: FWM can generate entangled photons needed for quantum communication and quantum computing. Spectroscopy: FWM techniques such as Coherent Anti-Stokes Raman Spectroscopy (CARS) provide enhanced sensitivity for chemical and biological sensing at the nanoscale.
