Abstract:
1. A packaging for an opto-electronic device, comprising: a body; a first optical transmitter die configured to emit light; a first optical receiver die configured to receive a portion of the light emitted by the first optical transmitter die; a conductive pad, the conductive pad having a component side and an opposing side that opposes the component side with at least one of the first optical transmitter and receiver dies being mounted on the component side of the conductive pad; a first light guide configured to transmit light adjacent to the component side of the conductive pad, from the first optical transmitter die to the first optical receiver die; a limiting element configured to confine the first light guide to the component side of the conductive pad when the first light guide is in liquid form prior to being hardened into solid form so as to substantially eliminate light transmission along the opposite side of the conductive pad; an attachment layer sandwiched between the opposing side of the conductive pad and the limiting element; and an opaque encapsulant encapsulating the first light guide and the limiting element forming the body.
