摘要 | In order to start sweeping an optical spectrum analyzer 1 and a wavelength tunable light source 14 on the same timing, a motor 6 for driving a spectroscope 4 in the optical spectrum analyzer 1 is controlled. To this end, a drive circuit 7 outputs a control signal to determine the timing where the motor 6 starts to rotate. A wavelength control circuit 19 in the wavelength tunable light source 14 controls the sweep of the wavelength of single-mode oscillation from a light source unit 20 and starts sweeping the light source unit 20 in response to a signal externally supplied to control the timing of sweep start. As a result, the sweep of the wavelength being measured with the optical spectrum analyzer 1 and that of the wavelength of single-mode oscillation from the wavelength tunable light source 14 are started on the same timing and high-speed sweep is achieved. |

主权项 | A wavelength tracking system using an optical spectrum analyzer and a wavelength tunable light source that measures light wavelength characteristics using an optical spectrum analyzer that measures the spectra of optical signals and a wavelength tunable light source that can output light at different wavelengths, in which the timing of starting the rotation of a motor for controlling the drive of a spectroscope in said optical spectrum analyzer that extracts a specified wavelength by spectral resolving is allowed to coincide with the timing of starting the sweep of a single-mode oscillating wavelength from a light source unit in said wavelength tunable light source, and control is so performed as to attain wavelength coincidence within the range of measurement during continuous and high-speed sweep. |
