ABSTRACT:
This invention relates to an electro-optic modulator device, such as a multi-gate light valve for an electro-optic line printer, wherein the different elements are uniquely combined in a package utilizing VLSI principles. A specially designed integrated circuit package is utilized to enable the bonding of one or two electro-optical devices as a single unit. As each electro-optical device has its chip pads at one end of the device, special modifications need to be made to joint the pads to the external connectors. The electro-optical crystal, which may be mounted on a glass plate, is bonded to the integrated circuit chip. Sonic bonding or the two layer metal technique may be used for the crystal to chip bonding.
