Based on the leakage and measurement of evanescent wave in side-polished fiber (SPF),an all-fiber integrated optical power monitor-controller (OPMC) is fabricated by integration of variable optical attenuator (VOA) and optical power monitor (OPM). Using common optical fiber as a substrate of waveguide,the structure of OPMC based on dual side-polished areas of side-polished fiber is designed,and its manufacture technique is developed. A VOA and an OPM are fabricated in the first and second polished areas of side-polished fiber,respectively. Both VOA and OPM are integrated in a section of optical fiber so as to become an all-fiber integrated photoelectronic component that has two functions of both monitor and controller. Experiments show that the typical characteristics of the integrated component are as follows:insertion loss of 0.7 dB,attenuation range of 0-52 dB,wavelength dependent loss of 0.2 dB,polarization dependent loss of 0.17 dB,photoelectric transition efficiency of larger than 100 mA/W,and so on. The all-fiber integrated component has many advatages,such as easy fabrication,small size,low cost ,electric control,etc.
