Claim 0:
1. A method of fabricating a blazed diffraction grating, the method comprising:
providing a master template substrate;
imprinting periodically repeating lines on the master template substrate in a plurality of master template regions, wherein the periodically repeating lines in at least two of the master template regions extend in different radial directions with respect to an axis that is orthogonal to a surface of the master template substrate; and
using at least one of the master template regions as a master template to imprint at least one blazed diffraction grating pattern on a grating substrate,
wherein the periodically repeating lines in adjacent ones of the master template regions extend in different directions that form an angle greater than zero and less than 90 degrees.
