The lasers emit at »850 nm, which is the most commonly used wavelength for short-reach (<2 km) optical data communication across multiple-mode optical fiber. Our devices present state-of-the-art electrical and optical parameters, e.g. high room-temperature maximum optical powers of over 5 mW, laser emission at heat-sink temperatures up to at least 95°C, low threshold current densities (<10 kA/cm2) and wall-plug efficiencies exceeding 30% VCSELs can also be easily adjusted to reach emission wavelengths of around 780 to 1090 nm.}, type={Article}, title={First vertical-cavity surface-emitting laser made entirely in Poland}, URL={http://www.journals.pan.pl/Content/119722/PDF/30_02059_Bpast.No.69(3)_24.06.21_Druk.pdf}, doi={10.24425/bpasts.2021.137272}, keywords={semiconductor laser, GaAs, optical communication, VCSEL}, }
