Abstract :
The threshold current in 20 ¿m stripe GaxIn1¿xAsyP1¿y lasers operating at 1.3 ¿m wavelength decreases with increasing pressure, whereas the opposite effect occurs in lasers made of Ga1¿xAlxAs The magnitude of the change observed in quaternary lasers is consistent with the presence of intervalence band absorption or Auger recombination, but not with the other mechanisms considered.
