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.
Claims15
A method of manufacturing an optoelectronic device, comprising:
- encapsulating an emitter of light rays in a first transparent block;
- forming a layer at least partially covering an upper surface and a side surface of the first transparent block, said layer being opaque to wavelengths of light rays emitted by the emitter;
- mounting a receiver of light rays to said layer at the upper surface of the first transparent block.
