| 英文摘要 | The present invention provides a light generation methodand a light source that are preferable in obtaining a single-modelight having high outputs, a small wavelength spectral bandwidth,and a low intensity noise. A white output from a white-lightsource and having wavelength components over a wide-band in awavelength spectrum passes through an isolator and is thenfiltered by a disc-shaped optical filter. A transmitted lightis input to a semiconductor optical amplifier having itspolarization plane regulated by a polarization controller. Anoutput from the amplifier passes through an isolator and is thenfiltered by a disc-shaped optical filter again to generate asingle-mode light having a small spectral bandwidth and highoutputs. Polarization control by the polarization controllercorresponds to control of the polarization plane of asemiconductor laser in the semiconductor optical amplifier soas to obtain a maximum gain from the amplifier. Thisconfiguration enables a single-mode light having a smallspectral bandwidth and high outputs to be easily generated atan arbitrary wavelength. |
