Auto Test System For Semiconductor Optical Amplifier

With the rapid development of telecommunication, the optical-communication now has good development opportunity than it ever before. Under the situation keeping growing of the need of the optical device and the optical-communication industry, our optical device producer must resolve the problem that will be found during volume-produce. The most important one is that the testing of the optical device. The traditional way is based on device's single performance, the tester must connect the instruments and the optical path, and than test the performance manually. If it is necessary to test the device's other performance, the tester must connect different instruments and optical path. So, this method will take a lot of time and has low precision.The content of this dissertation is based on the"863"project"the technology of mass production of high performance semi-conductor amplifier". This dissertation introduces an auto-test system of SOA(semiconductor optical amplifier). This system is based on GPIB (General Purpose Interface Bus). The computer controls the test instruments at real time to achieve the test to the SOA automatically, the computer can help the tester to deal with the data of the test and analyze the result, and save the test report as electronic files expediently.This dissertation expatiates the principle of the GPIB and the controlling processes. At the same time, this dissertation expatiates the hardware and the software composing, make a contrast between the system's test result and the manual test result.This system has friendly graphic user interface, the tester only need to fill some test parameter. Because there is no interference after the connection of the instruments and the optical path, it reduces the test error, and saves the tester's time. This system has good ability to be extended. By loading different instruments library, it can test a lot of kinds of optical devices.
