Abstract
Wavelength-based optical power provisioning is provided by multiplexing a plurality of continuous wave light beams at different wavelengths onto a single optical fiber as a multiplexed light source and demultiplexing the multiplexed light source based on wavelength at a photonic unit coupled to the optical fiber to recover the continuous wave light beams. The recovered continuous wave light beams are split into a plurality of light beams by the photonic unit, each light beam having the same wavelength and the same or lower power as one of the recovered continuous wave light beams so that at least one of the light beams generated by the photonic unit has a higher power than the other light beams generated by the photonic unit.
