Abstract
The seamless integration of customized micro-optical components into light-sensitive devices remains a challenging task toward enhancing the performance of solar cells and photodetectors. In this talk, I will show how laser additive processes can help ease this problem. We use laser pulses for depositing microdroplets and microdisks at targeted positions on a substrate. Following a photocuring or thermal reflow process, these elements are converted into microlenses and microlens arrays whose geometry, size, and optical properties solely depend on the laser parameters and substrate used. The excellent optical quality of the so-fabricated micro-optics offers a promising route for next-generation optoelectronic systems.
