Abstract
The present invention provides an optical coupler comprising: a first optical prong; a second optical prong; an optical waveguide with which the first optical prong and the second optical prong merge; wherein: a distance from an axially outer tip edge of the first optical prong to an axially outer tip edge of the first optical prong is greater than a planar width of the optical waveguide; and the first optical prong and the second optical prong are each tapered from the optical waveguide.

An optical coupler comprising:
- a first optical prong;
- a second optical prong;
- and
- an optical waveguide with which the first optical prong and the second optical prong merge;
- wherein:
- a distance from an axially outer tip edge of the first optical prong to an axially outer tip edge of the first optical prong is greater than a planar width of the optical waveguide;
- and
- the first optical prong and the second optical prong are each tapered from the optical waveguide.
5 more elements
A suspended optical waveguide comprising:
- an optical waveguide;
- a trench parallel to and below a surface of the waveguide;
- bridging coupled to the optical waveguide and suspending the optical waveguide over the trench;
- and
- a plurality of walls angled with respect to the optical waveguide, each of the walls providing a fluid-tight seal across the trench.
