Abstract
Biointegrated microlasers can act as highly localized sensors and report minute refractive index changes from within living cells. We previously reported non-obstructive and biointegrated whispering gallery mode nanolasers made from high-index semiconductor materials. Arsenide-free III/V alloys are attractive for this application due to minimal toxicity and high performance at visible wavelengths. Here, the band gaps of GaInP/AlGaInP quantum wells were engineered for absorption and emission at (far)-red wavelengths, allowing sub-pJ pumping at 642 nm and two-photon pumping with lasing thresholds around 80 pJ. This facilitates the wider integration of the nanolaser technology with popular fluorescence and multiphoton microscopy techniques.
