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.
