Abstract :
Summary form only given. Vertical-cavity surface-emitting lasers (VCSELs) should play an important role in future optical data links. However, because polarization direction in conventional VCSELs is not determined, noise enhancement due to polarization switching by feedback light from optical fiber or other components becomes a serious problem. This paper presents for the first time, to our knowledge, that a transverse-mode polarization-controlled InGaAs QW VCSEL, is effective for lowering feedback light-induced polarization switching noise.
