Abstract:
1. An opto-coupler comprising: a first mold comprising an optically transparent material that encloses a first assembly comprising a first die mounted on a substrate, the first mold characterized by a pre-determined thickness between a first surface of the first die and a platform that is located on a first portion of an external surface of the first mold, the pre-determined thickness defined in part by a desired optical isolation performance of the opto-coupler and by an optical coupling efficiency of the optically transparent material, the first mold further characterized by a second portion of said external surface, the second portion configured to be at a different level with reference to the first portion; an adhesive material disposed on the first portion of the external surface of the first mold; and a second assembly comprising a second die that is affixed by the adhesive material to the platform located on the first portion of the external surface of the first mold.
