    • A wavelength stabilization module having a light-receiving element array and a method of manufacturing the same are disclosed. The wavelength stabilization module having a laser diode which irradiates a laser beam at the front side and the rear side thereof comprises a collimator for paralleling the laser beam irradiated at the rear side; a beam splitter for splitting the laser beam passed through the collimator into the two directional laser beams; a light-receiving element for receiving one of the split laser beams; a filter for transmitting a specific wavelength of the other of the split laser beams; a light-receiving element array for receiving the laser beam passed through the filter; and a controller for controlling the output wavelength of the laser diode by using the signals output from the light-receiving element and the light-receiving element array, and the filter and the light-receiving element array are tilted at a predetermined angle with respect to the laser beam and lock the wavelength by using an incident angle dependency of the laser beam passed through the filter.
    • 公开了具有光接收元件阵列的波长稳定模块及其制造方法。 具有在其前侧和后侧照射激光束的激光二极管的波长稳定模块包括用于与在后侧照射的激光束并联的准直器; 用于将穿过准直器的激光束分成两个定向激光束的分束器; 用于接收所述分离激光束中的一个的光接收元件; 用于传输另一个分离激光束的特定波长的滤波器; 用于接收通过过滤器的激光束的光接收元件阵列; 以及控制器,用于通过使用从光接收元件和光接收元件阵列输出的信号来控制激光二极管的输出波长,并且滤光器和光接收元件阵列相对于 激光束并通过使用通过过滤器的激光束的入射角依赖性来锁定波长。
