    • A system for monitoring an optical output/wavelength is employed to be used for a WDM system having a narrow channel space by structuring an etalon and photodiode as an integrated structure. The system includes: a laser source control unit for controlling the laser source; an optical/wavelength monitoring unit for monitoring an optical output/wavelength of the controlled laser source; a TEC control unit for controlling a TEC in order to constantly maintain the laser source of the optical output/wavelength monitoring unit to have a predetermined temperature; a temperature control unit for controlling a heater and a thermistor to set an etalon to a predetermined temperature, wherein the heater is attached on the optical output/wavelength monitoring unit and the thermistor is attached on the heater; a comparison unit for comparing the optical output signal and the wavelength signal, each of which is monitored by the optical output/wavelength monitoring unit; and a processing unit for comparing values of the compared signals with a preset value to control an input current or a temperature of the laser source.
    • 用于监测光输出/波长的系统被用于通过构造标准具和光电二极管作为一体结构而具有窄通道空间的WDM系统。 该系统包括:用于控制激光源的激光源控制单元; 用于监测受控激光源的光输出/波长的光/波长监测单元; 用于控制TEC的TEC控制单元,以便将光输出/波长监视单元的激光源恒定地保持为预定温度; 温度控制单元,用于控制加热器和热敏电阻以将标准具设定到预定温度,其中加热器安装在光输出/波长监测单元上,热敏电阻附着在加热器上; 比较单元,用于比较光输出信号和波长信号,每个波长信号由光输出/波长监测单元监视; 以及处理单元,用于将比较的信号的值与预设值进行比较,以控制激光源的输入电流或温度。
