Someya et al. recently reported [Jpn. J. Appl. Phys. 37 (1998) L1424] optically pumped laser operation from an InGaN-based vertical cavity surface emitting laser, which they characterize as the "the first unambiguous observation of laser emission by a III-V nitride VCSEL." They claim that our previous report of lasing in a GaN-based vertical cavity laser is attributable to phenomena other than vertical lasing. We argue against the plausibility the authors' unsubstantiated alternative explanation for our results, which forms the basis for their claim.
