US Patent 7492803 - Fiber optic coupled nanowire laser

http://www.freepatentsonline.com/7492803.html

This patent from Hewlett Packard introduces a single photon fiber optic system based on nanowire lasers which could be very important to quantum communication systems in the future. Claim 1 reads:

1. A device comprising:

a substrate having at least one hole;

a nanowire laser positioned within the at least one hole; and

a waveguide positioned proximal to said at least one hole so that a single photon generated by said nanowire laser is coupled into said waveguide.
