Modern Optics
Wavelength-division multiplexing (WDM) is a technology that allows multiple signals to be transmitted simultaneously over a single optical fiber by using different wavelengths (or colors) of laser light. This method significantly increases the capacity of fiber optic networks, making it possible to send large amounts of data over long distances without interference, and is particularly relevant in the context of nonlinear light-matter interactions where these wavelengths can interact with materials in complex ways.
congrats on reading the definition of wavelength-division multiplexing. now let's actually learn it.
