Language: | eng | Issue Date: | Sep-2006 | Publisher: | Soc. | Document Type: | Article | Journal / Series / Working Paper (HSU): | Optics letters | Volume: | 31 | Issue: | 18 | Page Start: | 2768 | Page End: | 2770 | Publisher Place: | Washington, DC | Abstract: | We demonstrate an experimental method for the direct measurement of band structures of one-dimensional periodic optical media. With the help of a prism coupler that is used in a retroreflective scheme, the allowed bands of a waveguide array in lithium niobate are determined and the results are compared with numerical calculations. Furthermore, we demonstrate the suitability of this method to measure propagation constants of extended nonlinear modes inside the forbidden gap. |
