abstract = {Vertical-cavity surface-emitting lasers (VCSELs) are as sensitive
to optical feedback (OF) as edge-emitting lasers as their much
higher mirror reflectivity is compensated by the much smaller
intracavity round-trip time resulting in a similar OF rate.
VCSELs may emit light in multiple transverse modes and may
exhibit polarization bistability which adds new features to their
behavior when subject to OF. We present a survey on experimental
and modeling results for three regimes of OF in VCSELs: long,
short, and extremely short external cavities (ECs). We show that
for long and short ECs, the Lang-Kobayashi model is in good
agreement with experiments on OF-induced polarization switching,
mode hopping, and antiphase oscillatory dynamics at the delay
time. These last dynamics modify polarization residence-time
distribution making it oscillatory. We demonstrate numerically
and experimentally coherence resonance in such bistable,
time-delayed optical system. We present results on low-frequency
fluctuation and pulse-package dynamics in VCSELs and discuss the
role of light polarization. We discuss polarization rotating OF
for generating high-frequency pulses as a result of EC mode
beating. Finally, we demonstrate how OF from extremely short EC
can strongly modify VCSEL characteristics and can be used to
effectively control their polarization properties by
subwavelength changes of the EC length.}
