Study Of Optical Power Splitter Based On Ion-exchange On Glass

In view of the thread of the informational and network society, communication capacity is increasing dramatically. In the situation the optical communication gets vast space to develop. Especially FTTH will rise to whip up a new round of the optical communication network building to a climax. As a key optical network devices, optical power splitter is therefore of great significance.Glass based ion-exchanged technology is a good choice of large-scale production of optical power splitter. Moreover, in many other important areas it has many potential applications, such as waveguide amplifiers, sensors.In this paper, we have a systematical research on the glass based ion-exchanged technology. In the use of it, we realize the low-loss buried single-mode waveguide and 1x8/16/32 power splitter which have partially reached production standard. In order to adapt the future developments, we analysis how to reducing the splitter size additionally. It laid the groundwork of the future development of smaller device.Utilizing the 1x3 splitter unit, we can make much more kinds of optical power splitters. In this paper we also have a research on 1x3 splitter unit. After the design and realization we analysis the problem of it. At last we discuss the issue of device production tolerance and then take out a idea to improve it which named' Tolerance Compensation'.In the end of the paper, we have a more in-depth research on the issue of 'multimode waveguide fabrication on glass' based on the original classmate's research. We choose the Ag~+- Na~+ ion exchange instead of Li~+- Na~+ ion exchange and get a good result.
