MODULES HAVING MULTIPLE OPTICAL CHANNELS INCLUDING OPTICAL ELEMENTS AT DIFFERENT HEIGHTS ABOVE THE OPTOELECTRONIC DEVICES

摘要

An optoelectronic module has multiple optical channels each of which includes a respective optical element at a different height within the module. The modules can include channels arranged side-by-side where each channel is covered by a respective cover that is optically transmissive to one or more wavelengths of light emitted by or detectable by the optoelectronic devices in the module. The transmissive covers, which respectively can include one or more passive optical elements on their surfaces, are disposed at different heights within the module.

主权项

1. An optoelectronic module comprising:
a support substrate on which are mounted first and second optoelectronic devices; a first transmissive cover over the first optoelectronic device at a first height above the support substrate; a second transmissive cover over the second optoelectronic device at a second height above the support substrate, the second height being different from the first height; exterior walls laterally encircling the first and second optoelectronic devices, the exterior walls composed of a material that is non-transparent to one or more wavelengths of light emitted by or detectable by the first and second optoelectronic devices; and an interior wall separating the first and second optoelectronic devices from one another, the interior wall being composed of a material that is nontransparent to one or more wavelengths of light emitted by or detectable by the first and second optoelectronic devices.
