Abstract:
In this paper, we present fixed-wavelength, verticalcavity-
surface-emitting lasers (VCSELs) based on InP with remarkable
single-mode (SM) output powers. It is shown that a
precise choice of the diameters of the ring geometry of the bottom
GaInAs intracavity contact layer severely affects the guiding
behavior of the fundamental and first-order modes inside the cavity.
Experimental data, statistics, and theories will be discussed on
how to overcome spatial hole burning and how to master thermal
guiding and efficient current injection in order to extend SM output
powers to beyond 8 mW at room temperature for VCSELs
with 7 ?m aperture. Coming along with side-mode suppression
ratios exceeding 50 dB and continuous electrothermal wavelength
tunings exceeding 8 nm, these laser devices define a new state of the
art of electrically pumped InP-based short-cavity long-wavelength
VCSELs at 1.55 ?m emission.
