  • Frequency shifting optical swept lightsource system and apparatus to which the system is applied
    Patent number: 9577400
    Abstract: Provided is a frequency shifting optical swept light source system. The system includes a light source that emits light; an amplifier that amplifies the light output from the light source; an optical converter that shifts a frequency of the amplified light and compresses a spectrum of the amplified light; and a controller that controls a current signal applied to the light source such that a repetition rate of the light output from the light source is adjusted, so that an intensity of the amplified light is adjusted, to thereby adjust a position of the compressed spectrum with respect to a predetermined frequency band.
    Type: Grant
