Polarization switching (PS) appearing in longwavelength
vertical-cavity surface-emitting lasers (VCSELs)
subject to orthogonal optical injection is investigated theoretically
and experimentally. We have studied the injected optical power
required for PS as a function of the frequency detuning between
the injected light and the orthogonal linear polarization of the
VCSEL. For a wide range of bias currents applied to the
device, the injected power required for the occurrence of PS
exhibited a minimum and a plateau with respect to the frequency
detuning. The minimum (plateau) was found at negative (positive)
frequency detuning. The bistable behavior of the polarization
is described. Our experimental results confirm the theoretical
predictions of Sciamanna and Panajotov. The levels of the
minimum and the plateau were observed to increase as higher
bias currents were applied to the VCSEL. A first theoretical
and experimental observation of the disappearance and further
appearance of PS when increasing the injected power in longwavelength
VCSELs is described. This situation is obtained
for small levels of negative frequency detuning and for large
enough values of applied bias current. A good overall qualitative
agreement is found between our theoretical and experimental
results.
