Choquette, Kent D. Fryslie, Stewart 2014-01-16T17:57:22Z 2014-01-16T17:57:22Z 2013-12 2014-01-16T17:57:22Z 2013-12 Microcavity laser design and performance optimization requires a quantitative knowledge of the cavity optical losses. A generalized method using sub-threshold spectral measurements matched to model calculations is demonstrated to determine optical loss in microcavity lasers. Cold-cavity spectral characteristics are used to extract the size dependent optical loss for small diameter oxide-confined vertical cavity surface emitting lasers. For oxide aperture diameters less than 4 !m, the oxide scattering loss can be greater than 10 cm-1, similar to the typical values of free carrier absorption loss.
