【Abstract】 The auto-aligning projects and the corresponding programs are designed. The primary optical-electromechanical integration and the interfaces with computer are accomplished. The auto-aligning experiment using single mode fiber for the communication as a standard waveguide was carried out. The results show that the average end-coupling loss and the standard deviation are 0.075 dB and 0.009 9 dB at wavelength of 1 310 nm, and 0.062 dB and 0.006 6 dB at 1 550 nm respectively. It takes less than 2 minutes to finish the whole auto-aligning process.更多还原
