Not Accessible

Your library or personal account may give you access

Abstract

Micro transfer printing of GaSb-based gain elements transferred to silicon photonics platform is reported for the first time. Using a distributed Bragg reflector fabricated utilizing silicon-on-insulator technology and the GaSb integrated gain chip, a single frequency external cavity laser emitting at around 1.96 µm is demonstrated.
