Title:
VERTICAL EMITTERS WITH INTEGRAL MICROLENSES
Document Type and Number:
WIPO Patent Application WO/2020/163139
Kind Code:
A3
Abstract:
An optoelectronic device (20) includes a semiconductor substrate (22) having first and second faces. A first array of emitters (24, 26) are formed on the first face of the semiconductor substrate and are configured to emit respective beams (28) of radiation through the substrate. Electrical connections (36, 38) are coupled to actuate selectively first and second sets of the emitters in the first array. A second array of microlenses (30, 76, 78) are formed on the second face of the semiconductor substrate in respective alignment with the emitters in at least one of the first and second sets and are configured to focus the beams emitted from the emitters in the at least one of the first and second sets so that the beams are transmitted from the second face with different, respective first and second focal properties.
