Abstract
Techniques for designing optical devices that can be manufactured in volume are disclosed. In an exemplary an optical assembly, to ensure that all collimators are on one side to facilitate efficient packaging, all collimators are positioned on both sides of a substrate. Thus one or more beam folding components are used to fold a light beam up and down through the collimators on top of the substrate and bottom of the substrate.
Claims15
An optical assembly comprising:
- at least a common collimator;
- a substrate;
- an array of channel collimators including an upper set of collimators and a lower set of collimators, wherein the upper set of collimators is mounted on top of the substrate, and the lower set of collimators is mounted on bottom of the substrate;
- one or more beam folding components mounted near an end of the substrate, wherein the one or more of the beam folding components turn a light beam traveling through the upper set of collimators to the lower set of collimators, or a light beam traveling through the lower set of collimators to the upper set of collimators, wherein all of the collimators and the common collimator are on one side of the beam folding components.
