Abstract :
We have demonstrated a simple yet effective spectrometer. It uses chirped supercontinuum pulses as a broadband source and a sampling oscilloscope or A/D converter for spectral analysis. Distinct advantages for this system include the absence of an optical spectrometer, the broad spectral bandwidth available from the supercontinuum source, and the possibility of real time spectral analysis. A passively mode locked erbium doped fiber laser with a pulse compression stage was used as the supercontinuum source
