| 英文摘要 | In an optical wavelength control circuit, an activation control circuit outputs an optical output setting signal to a laser unit to set its optical output, and simultaneously outputs a temperature setting signal and a wavelength setting signal. A temperature error detection circuit outputs a temperature error signal. A wavelength error detection circuit outputs a wavelength error signal. A control switching circuit receives the temperature error signal and the wavelength error signal, selectively outputs the temperature error signal as a control error signal in the activation operation, and selectively outputs the wavelength error signal as the control error signal in a steady-state operation after the activation operation. A steady-state error removing circuit removes a steady-state error contained in the control error signal and outputs a temperature controller control signal. A temperature controller driving circuit drives a temperature controller of the laser unit in accordance with the temperature controller control signal. |
