Flexible InGaAs/InAlAs avalanche photodiodes for short-wave infrared detection.

ABSTRACT: Flexible detectors have gained growing research interest due to their promising applications in optical sensing and imaging systems with a broad field-of-view. However, most research have focused on conventional photodiodes of which the responsivity are limited at short-wave infrared due to the absence of internal multiplication gain. Here we have realized and demonstrated flexible thin-film InGaAs/InAlAs avalanche photodiodes on a mica substrate for short-wave infrared detection. This achievement was made possible by the development and implementation of a low-temperature bonding and well-optimized fabrication process. Our devices exhibit promising characteristics, including low dark current, good responsivity, and high multiplication gain. Even when subjected to bending conditions, the a
