Abstract
Abstract An application-specific rf optoelectronic integrated circuit having a generic chip member and a defining substrate in communication with at least one generic chip member. The generic chip member contains passive building block components that are independent from each other and being connected by paths external to the generic chip member. The external connection paths are defined by a defining substrate member having passive components for providing optical and electrical interconnection between selected building block components on the generic chip member to define the specific function of the integrated circuit. It is possible to use the same design of the generic chip for several applications merely by altering the interconnect paths on a defining substrate.
