Abstract
An optoelectronic device includes an emitter of light rays and a receiver of light rays. The emitter is encapsulated in a transparent block. An opaque conductive layer is applied to a top surface and a side surface of the transparent block. The receiver is mounted to the opaque conductive layer at the top surface. An electrical connection is made between the receiver and the opaque conductive layer. A conductive strip is also mounted to the side surface of the transparent block and isolated from the opaque conductive layer. A further electrical connection is made between the receiver and the conductive strip.
Claims28
An optoelectronic device, comprising:
- a support having a top surface including a first electrical pad, a second electrical pad and a third electrical pad;
- an emitter mounted to the top surface of the support and electrically connected to the first electrical pad;
- a first transparent block mounted to the top surface of the support and encapsulating the emitter and the first electrical pad;
- a first layer of conductive material extending on a side surface and a top surface of the first transparent block, said first layer of conductive material electrically connected to the second electrical pad;
- a receiver mounted to the first layer of conductive material at the top surface of the first transparent block;
- a second layer of conductive material extending on said side surface of the first transparent block, said second layer of conductive material electrically connected to the third electrical pad and to the receiver.
An optoelectronic device, comprising:
- an emitter of light rays;
- a receiver of light rays;
- a first transparent block encapsulating the emitter;
- and
- a layer on a top surface of said first transparent block, wherein said layer is opaque to wavelengths of the light rays from the emitter, and wherein the layer extends partially over said emitter;
- wherein the receiver is mounted to said layer at the top surface of said first transparent block.
An optoelectronic device, comprising:
- an emitter of light rays;
- a first transparent block encapsulating the emitter and having a top surface and a side surface;
- a second transparent block mounted to the top surface of the first transparent block over the encapsulated emitter and having a side surface;
- a first layer that is opaque to wavelengths of the light rays from the emitter and which extends on the top side and side surface of the first transparent block and further extends on the side surface of the second transparent block;
- and
- a receiver of light rays mounted on the first layer over the top surface of the first transpatent block.
