摘要： Various embodiments of the present invention are directed to photonic interconnects that can be used for on-chip as well as off-chip communications between computer system components. In one embodiment of the present invention, a photonic interconnect (108) comprises a plurality of on-chip waveguides (308). Additionally, the photonic interconnect may include a plurality of off-chip waveguides (310,620), and at least one optoelectronic converter (306). The at least one optoelectronic converter (306) can be photonically coupled to a portion of the plurality of on-chip waveguides (308), can be photonically coupled to a portion of the plurality of off-chip waveguides (310,620), and is in electronic communication with at least one computer system component (615-618).

摘要： An optical apparatus (100), an optical system (200) and a method (300) of light amplification by stimulated emission employ an endohedral metallofullerene (120, 220) as an active material coupled to an optical waveguide (110, 210). The endohedral metallofullerene (120, 220) is optically coupled to an optical field of the optical waveguide (110, 210). The coupled optical field produces a stimulated emission in the endohedral metallofullerene (120, 220). The optical system (200) further includes an optical source (230) that generates optical power (232) to pump the endohedral metallofullerene (200) to produce a stimulated emission. The method (300) further includes optically pumping (330) the coupled endohedral metallofullerene by introducing an optical pump into the optical waveguide.

摘要： An optical engine (11) for providing a point-to-point optical communications link between devices. The optical engine (11) includes a light source (24) optically coupled to a modulation chip (6) and configured to generate an optical beam. The optical engine further comprises a modulator (21) carried on the modulation chip and configured to modulate the optical beam. The optical engine further includes a waveguide (30), formed in a plane parallel to the plane of the substrate, and configured to guide the modulated optical beam from the modulator to at least one of a plurality of out-of-plane couplers (40) grouped in a defined region (48) of the modulation chip. The out-of-plane coupler can couple the modulated optical beam to an optical device.
