Abstract： |
A process for preparing transmission (or reflection)-type controllable high-chirp optical-fibre raster includes preparing more rasters on an optical fibre by scan writing method with different exposing intensities, measuring and recording the relation between exposing intensity and transmissivity (or reflectivity), creating database, calculating the ralation between the exposing intensity and the transmissivity needed by user according user requirement, and preparing the said raster by scan writing method and controlling the exposing time. |
