A split microprocessor socket is disclosed that provides a cavity created at an outer edge of the microprocessor socket. An optical module may be fitted in the cavity thus providing an optical fiber or waveguide connection directly to the socket. This low cost optical interconnect, closely packaged with the microprocessor, may alleviate bandwidth constraints associated with conventional electrical connections.

A temperature sensing and control method and apparatus. In one aspect of the present invention, an apparatus according to the teachings of the present invention includes an optical path disposed in semiconductor material. A four-terminal resistor is defined in the semiconductor material. At least a portion of the optical path is directed through the four-terminal resistor.
