With the use of atomic force microscopy (AFM) we show excellent agreement between theoretical predictions and actual measurements. From this analysis, we have developed a level of confidence in future facet roughness calculations based on data obtained through slope efficiency and far field data. Our rms facet roughness is 220 /spl Aring/, well below the industrial standard. We have also measured the facet vertically to be 2" which, to our knowledge, is the best to date for methane-based InP laser facet etching.
