Özet:

 

We present the results of our studies concerning the pulsed  operation of a bulk GaInAsP/InP vertical cavity surface emitting laser  (VCSEL).  The device is tailored to emit at around 1.5 m m at room  temperature.  The structure has a 45 period n-doped GaInAsP/InP bottom  distributed Bragg reflector (DBR), and a 4 period Si/Al2O3  dielectric top reflector defining a 3-l cavity.   Electroluminescence from a 16 m m diameter top window was measured  in the pulsed injection mode.  Spectral measurements were recorded in  the temperature range between 125K and 240K. Polarisation, lasing  threshold current and linewidth measurements were also carried out at  the same temperatures.  The threshold current density has a broad  minimum at temperatures between 170K and 190K, (Jth=13.2 kA/cm2),  indicating a good match between the gain and the cavity resonance in  this temperature range.  Maximum emitted power from the VCSEL is 0.18  mW at 180K.
