VCSEL,
vertical cavity surface emitting laser is
one of the semiconductor lasers with the light
emission through vertical direction. The laser
structure is consisting of vertically stacked
mirrors
with an active gain region. Those emitting
structure provides several advantages in both
perfor-
mance and cost, compared to conventional edge-emitting
laser. Accordingly, VCSELs have been
recognized as a next generation light source
for both telecommunications and data communications.
Raycan owns key technologies for fiber-optic
components, especially VCSELs in both epitaxial
growth and device fabrication. The thick VCSEL
structure, vertically stacked DBRs and active
region,
requires precise and reproducible epitaxial
growth control with VCSEL-oriented fabrication
technology.
With over 10 years experiences of semiconductor
optoelectronic devices on VCSEL,Raycan enables
to full device manufacturing with our own
unique VCSEL technologies. In particular,
InP-based long-
wavelength VCSELs, defect free & lattice
matched, have mass-production favorable growth
and
fabrication processes, which are high-reliable
& reproducible technologies. |
