“…The results suggest that GaInNAs is suitable as the gain medium of a small cavity structure. The reported case of GaInN shows strong potential disorder within the system and hence the diffusion of the carriers is small, 15,18,19,25) inducing a small surface recombination velocity at the edge of the processed air hole.…”

We investigate the function of a circularly arranged submicron-scale optical cavity having a GaInNAs gain medium introduced into a two-dimensional photonic crystal slab. GaInNAs gain shows negligible optical degradations due to process damage, probably because of the small surface recombination velocity of the material. The preserved optical property realizes the observation of spectral peaks related to the cavity mode at wavelengths close to 1.3 µm. Moreover, the cavity shows fine tunability of its characteristics via the deliberate adjustment of its structure.

In this work we present detailed studies of the influence of nitrogen and antimony on the optical quality of InNAs(Sb) alloys. We employed photoluminescence, photoreflectance and positron annihilation spectroscopy to reveal the role of antimony and nitrogen on the improvement/degradation of the optical qualities of InNAs(Sb) alloys. A series of 1 μm-thick InNAs(Sb) layers with different nitrogen and antimony concentrations were grown by molecular beam epitaxy. The results of these investigations show that Sb atoms serve as a surfactant which effectively improves the optical quality of InNAsSb alloys. The influence of nitrogen on the optical quality however is not the same as to what has been reported for other dilute nitrides. We observed an improvement of the optical quality for some nitrogen contents. These issues are comprehensively examined and explained.
