<p>A method of patterning a plurality of optical rods includes bonding a plurality of optical rods into an array wherein each of the optical rods is aligned so that an exposed end face of each of the optical rods L(41) is oriented in a common direction. The exposed end faces of the optical rods are patterned (43) so that each of the exposed end faces has a three-dimensional pattern formed thereon. These patterned optical rods can then be separated and used in the fabrication of optical systems. A large number of optical rods can thus be patterned simultaneously using photolithographic mask and etch steps. More particularly, each of the optical rods can be a glass rod, and the three-dimensional patterns can be diffractive optical patterns, refractive optical patterns, and/or patterned layers. These various optical patterns can be used to provide beam shaping functions, pattern generation functions, diffusion functions, collimating functions, focusing functions, and/or wavelength division multiplexing functions. The plurality of optical rods can be bonded into a closely packed array using an epoxy.</p> |
