英文摘要	PURPOSE:To stabilize the oscillation frequency of LD and obtain a light source for wavelength multiplex optical communication with high multiplexing level by forming an external photo resonator of a particular wavelength for each LD, integrating an optical system using an optical glass block, detecting variation of power of 0th order diffracted light at the flat diffraction lattice and giving feedback to a drive circuit of LD. CONSTITUTION:An feedback optical system is integrated using an optical glass block. It is then bonded to the end surface of optical glass block 20 with a bonding agent such as ultraviolet ray setting resin by using a condenser rod lens for each collimeter lens and condenser lens. An output end of optical fiber 2 to guide each optical output of LD1 is arranged and bonded to the specified position on the focal point surface of condenser rod lens 15, and an optical feedback mirror 6 for selecting the oscillation wavelength is arranged and bonded to the specified position on the focal point surface of condenser rod lens 16 to select the oscillation wavelength of each LD The 0th order diffracted light scattered by the flat diffraction lattice 4 is focused on the focal point surface of condenser rod lens 17, it is converted to an electrical signal by a light receiving element array 18 to detect intensity variation of each LD Thereby, negative feedback effect can be applied to the LD drive circuit.
