Abstract
Systems and methods of side coupling, side illumination or side injection (as opposed to axial coupling, illumination, or injection) of a waveguide are disclosed. More particularly, it relates to increased coupling, by orders of magnitude, and, consequently, increased transmission, along a waveguide, of any wave by side coupling, side illumination, or side injection.
Claims6
A system for coupling a beam of light into a collection waveguide having a side surface disposed between first and second ends, the system comprising:
- at least one light source configured to generate the beam;
- a device configured to orient the beam towards the side surface of the collection waveguide at an angle off normal;
- and
- a detector at one of the first and second ends of the collection waveguide, the detector configured to detect the beam exiting from the one of the first and second ends;
- wherein said device comprises at least one hole extending through the device between a first surface adjacent the collection waveguide and a second surface opposite the first surface, the at least one hole extending at an angle relative to the first surface and configured to orient the beam toward the collection waveguide at the angle off normal.
