Abstract

This work demonstrates camera‑based detection of sub‑threshold and above-threshold modal features in quantum dot supraparticle lasers via analysis of the far‑field spatial emission patterns. This approach enables spectrometer‑free readout leveraging modal radiative signatures, highlighting its potential for applications in chemical/ biological detection and sensing.
