Abstract
Embodiments of the present invention are directed to a dual stage modular optical device for sending and/or receiving optical signals. A first fabricated package includes a light source for generating optical signals and/or a light detector for detecting received optical signals. A second fabricated package includes an opening for accepting circuitry that is to electrically interoperate with the light source and/or light detector to transfer optical signals. A lead frame mechanically connects the first fabricated package to the second fabricated package and electrically connects the light source and/or light detector to contacts exposed in the opening. The dual stage modular optical device can be coupled to a substrate configured to be received within a standard slot of a host system, such as a PCI or PCMCIA slot. Thus, one or more optical connections are integrated within the host device or system.
