| Talk Title: | Real-time characterization for optimally inducing electro-optical effects using thermal poling of twin-hole fiber |
| Slides: | 6-4.ppt |
| Abstract: | Silica fibers are the key components in transport links of optical networks. But as silica lacks electro-optical (EO) effects, it is limited only to be used in passive devices. By thermally poling silica fibers, e.g. by heating up the fiber and applying high voltage, the fiber becomes electro-optically active, which allows it to be used as the basic components of various active devices such as optical switch/modulator and wavelength converter. In my research project, a twin-hole fiber will be poled at ~300C temperature with ~5kV DC voltage while the evolution of the induced EO effects will be simultaneously characterized using interferometric methods. By analyzing the characterization results, poling conditions will be optimized to achieve the largest EO effects in the fiber core. |
