Abstract:
A microelectronics package, comprising:a chip including an electronic circuit that provides and receives electric signals, the chip including a first converter coupled to the electronic circuit and operable to receive an electric signal from the electronic circuit and convert the electric signal into a corresponding output electromagnetic wave, and/or operable to receive an input electromagnetic wave and convert the input electromagnetic wave into a corresponding electric signal that is applied to the electronic circuit; and a chip package physically coupled to the chip without an electrical connection bonding the chip to a signal lead on the package, the chip package including a second converter that is operable to receive the output electromagnetic wave from the first converter and convert the received output electromagnetic wave into a corresponding output electric signal, and/or operable to receive an input electric signal applied to the chip package and to convert the input electric signal into the input electromagnetic wave and communicate the input electromagnetic wave to the first converter, the first converter and the second converter being spaced apart and wherein the electromagnetic waves are directed along a beam path extending between the first converter and the second converter whereby the chip communicates signals to and from the package to which it is physically coupled without use of electrical couplings.
