Title: | Erbium-doped waveguide devices for WDM applications | Authors: | Federighi, Marco Othman, Noor Di Pasquale, Fabrizio |
Issue Date: | 1998 | Abstract: | Considerable advances have been made in the study of Er-doped waveguides for telecommunications application. These devices have been developed to allow on-chip integration between active and passive components, and differ from Er-doped fiber amplifiers in their much smaller size. To be of any use, these devices must provide gains of the order of a few dB/cm, which can be achieved with Er concentrations of about 1020 ions/cm3, or about an order of magnitude higher than in fibers. Furthermore, they should be fabricated at low temperature or co-doped with Al or P oxides to prevent Er ion pair formation. | URI: | http://dspace.uniten.edu.my/jspui/handle/123456789/8335 |
