Abstract:
1. A system of integrating electronic and optical functions comprising: an electronic chip that includes monolithic IC electronics for performing electronic functions and a plurality of trans-impedance amplifiers, said electronic chip including a plurality of solder bumps for receiving input for processing, said trans-impedance amplifiers are coupled to a selective number of said solder bumps by way of small wires, wherein ILD layers are interposed between the solder bumps of the electronic chip and said trans-impedance amplifiers; and an optical chip that receives an optical signal and performs optical functions on said signal, wherein said optical chip outputs electrical signals indicative of the optical functions performed on the signal, said optical chip including a plurality of solder bumps for sending said electrical signals as input to said electronic chip; wherein the solder bumps of said electronic chip and said optical chip are bonded to together so that a hybrid integration is formed that separates the yield of the optical and electrical circuits forming said electronic and optical chip.
