Abstract
A reconfigurable spectroscopy system comprises tunable lasers and wavelength lockers to lock to accurate reference wavelengths. Band combiners with differently optimized wavelength ranges multiplex the optical signal over the time domain, to emit a plurality of reference wavelengths for spectroscopy applications. The power requirements are greatly reduced by multiplexing over the time domain in time slots which do not affect sampling and receiving of the spectroscopy data.
