Feb. 1, 1999

Long phase mask

The LPM Series long phase mask has a 100-mm grating length and eliminates the stitching or phase error associated with the E-beam mask technology, according to the manufacturer, making it suitable for fabricating dispersion-compensation fiber gratings with a group delay ripple of <۱ picoseconds. The mask is also suitable for producing very high-reflectivity fiber Bragg gratings. The masks are available in constant period and linear chirp.
