Patent ID: 8778589

Claim:
A printing method of manufacturing a waveguide device comprising: depositing a first layer of toner to form a base layer; depositing a second layer of toner on the base layer to form a pattern of channels extending from openings at one edge of the second layer to exits on the device; filling the channels with a higher index of refraction material; depositing a top layer of laminate over the pattern of channels; and fusing the deposited first and second toner layers so that the laminate adheres to the fused toner of the second layer to provide an interface around the channel; wherein the higher index of refraction material has a higher index of refraction than the toner and the laminate, so that light that is injected into the higher index of refraction material from the opening in a direction that is approximately parallel to the channels will hit an interface between the higher index of refraction material and the fused toner and laminate only at high angles to cause the light to reflect within the channels and exit the channels through the exits on the device.
