Abstract
An optical communication device having multiple light sources under a single lens. The optical communication device has two light sources. The optical communication device has a lens optically coupled to the two light sources. The lens is shaped to direct light from the two light sources towards an axis of the lens. The optical communication device further has a third light source located below the approximate center of the lens.
Claims38
A communication device comprising:
- two light sources;
- a lens optically coupled with said two light sources;
- and
- wherein said lens is shaped to direct light from said two light sources towards a first axis of said lens.
1 more element
A communication device comprising:
- first and second light sources;
- a third light source;
- and
- a lens optically coupled to said first, second, and third light sources, said lens having an aspherical profile along a first axis and a substantially spherical profile along a second axis substantially perpendicular to said first axis, wherein said first and second light sources are located substantially along said first axis.
1 more element
A transceiver comprising:
- two light sources;
- a lens optically coupled to said two light sources and having a central axis;
- wherein said two light sources are positioned with respect to said central axis such that a combined light intensity profile from said two light sources is symmetrical about said central axis.
