Summary:A broadband light source includes an optical amplifier having amplifying mediums connected in series outputs an amplified spontaneous emission light over a wide wavelength range forward or backward. A circulator connected in series to the optical amplifier returns back to the amplifier spontaneous emission light outputted backwardly from the amplifier. A first pumping means located between the circulator and the optical amplifier pumps a pumping light to the optical amplifier, and a second pumping means located after the optical amplifier pumps a pumping light to the optical amplifier.
