First Vertical-Cavity Surface-Emitting Laser Made Entirely In Poland
BULLETIN OF THE POLISH ACADEMY OF SCIENCES-TECHNICAL SCIENCES(2021)
摘要
The paper presents the first vertical-cavity surface-emitting lasers (VCSELs) designed, grown, processed and evaluated entirely in Poland. The lasers emit at similar to 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 degrees C, low threshold current densities (< 10 kA/cm(2)) and wall-plug efficiencies exceeding 30% VCSELs can also be easily adjusted to reach emission wavelengths of around 780 to 1090 nm.
