Abstract
We investigate the possibility to achieve band-edge
lasing in optically thick gold-clad photonic-crystal membranes,
with a dielectric thickness of around 1 µm. We have performed
a two-dimensional eigenmode-expansion analysis of bandedge
resonators in one-dimensional photonic crystals. Material
thresholds, quality factors and emission efficiencies have been
calculated for TE band-edge laser resonances on the second and
third Gamma-point. The second Gamma-point sustains band-edge laser modes
with quality factors above 2500 for a membrane thickness of
1 µm and a cavity length of 20 periods, however with a very
poor surface-emission efficiency. Band-edge laser modes located
on the third Gamma-point have lower quality factors but higher surfaceemission
efficiencies. In both cases, the photonic crystal should
be designed specifically to avoid coupling with lossy, higher order
modes. Related Research Topics
