Micro‐Transfer Printing of GaSb Optoelectronics Chips for Mid‐Infrared Silicon Photonics Integrated Circuits (Adv. Mater. Technol. 10/2025)

In article number 2401791, Heidi Tuorila and co-workers present a micro-transfer printing concept by synthetizing the fabrication and device operation as a light source into a single illustration. The action occurring at the illustration indicates the stamping of the gain coupons on a silicon photonics platform with a flexible stamp. The illustration emphasizes the capacity of the technique to provide a compactly integrated multiwavelength light source.
