Abstract:
1. An optical logic device comprising: a laser comprising an optical resonator and a quantum dot therein, said optical resonator comprising counter-opposing microstructure-doped mirror portions, said quantum dot disposed between said mirror portions, said microstructure-doped mirror portions comprising of a plurality of microstructures disposed in an optically transmissive structure; an optical pump disposed with respect to said optical resonator to pump said quantum dot; at least one optical input port to couple light into said laser; and at least one optical output port to couple light out of said laser; wherein said laser has at least a first state and a second state that affect a characteristic of light coupled out said at least one optical output port, light coupled into said at least one optical input port switching said laser from said first state to said second state.
