Abstract

Special characteristics of very-small-aperture lasers are observed, including threshold current change, red shift of the spectral position, and short lifetime at low drive current. Physical mechanisms that underlie these special characteristics are analyzed: we find that optical feedback caused by a metal film and heat accumulation inside the laser diode lead to the special characteristics of VSALs, such as threshold current change, red shift of the spectral position, and short lifetime at low drive current, etc. Theoretical simulation is in good agreement with the experimental results.
