Bridging the VCSEL-Sensing Divide:
In-House Innovation for Optimized Solutions

A longstanding gap between Vertical-Cavity Surface-Emitting Laser (VCSEL) design standards and sensing requirements—such as output power, linewidth, and temperature performance—has hindered progress in advanced sensing.

Mesa Quantum bridges this divide by integrating VCSEL and sensing expertise under one roof, delivering tailored solutions for quantum, biomedical, and consumer markets. We’re setting new standards for photonics innovation.

An electromagnetic spectrum showing wavelengths. They include: 650/800 760/795 850 905/940 1130

Multijunction VCSELs

A graphic of a multijunction VCSEL. At the top is light,c oming out of the Anode layer. Directly below that is the SiN laer. Below that is p-DBR At the apeture layer, there is the oxide layer, followed by, MQWs, then the Tunnel Junction. Next is the n-DBR. Finally, there's the n-GaAs Substrate, with the Cathode at the bottom
