A long wavelength vertical cavity surface emitting laser having a
substrate, a first mirror situated on the substrate, an active region
situated on the first mirror, a second mirror situated on the active
region. The first mirror may have several pairs of layers with an
oxidized layer in one or more pairs of that mirror. The substrate may
include InP and the mirror components may be compatible with the InP. The
one or more layers in the first mirror may be oxidized via a trench-like
approach or other arrangement.
