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 a stimulated emission. The method (300) further includes optically pumping (330) the coupled endohedral metallofullerene by introducing an optical pump into the optical waveguide.

A system and method for an electrically pumped laser system is disclosed. The system includes a silicon micro-ring resonator 405. A quantum well 412 formed of a III-V group semiconductor material is optically coupled with the micro-ring resonator 405 to provide optical gain. A trapezoidal shaped buffer 414 formed of a III-V group semiconductor material and doped with a first type of carrier is optically coupled to the quantum well 412. A ring electrode 410 is coupled to the trapezoidal shaped buffer 414. The trapezoidal shaped buffer 414 enables the ring electrode 410 to be substantially isolated from an optical mode of the micro-ring resonator 405.

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.

Various embodiments of the present invention are directed to systems and methods for all optical distributed arbitration for computer system components (1801-1804) communicatively coupled via a photonic interconnect in a computer system device. The embodiments of the optical arbitration in the computer system provides arbitration schemes with fixed priority (2000) and non-fixed priority (1830, 2200). The non-fixed priority scheme embodiments can provide fairness in arbitration. In some embodiments, delivery of light power and arbitration are combined (1830, 2001).
