Distributed Bragg reflectors (DBRs) composed of In[sub 0.5]Al[sub 0.5]P/In[sub 0.5](Al[sub [ital y]]Ga[sub 1[minus][ital y]])[sub 0.5]P quarter-wave layers have been prepared using metalorganic vapor phase epitaxy. The structures were grown over a wide range of high-index layer composition (0[le][ital y][le]0.6) and peak reflectivity wavelength (720 nm[le][lambda][le]565 nm, covering the spectrum from deep red to green). In all cases observed and calculated reflectance spectra were in excellent agreement. Using these DBRs, an undoped all-phosphide visible vertical cavity surface-emitting laser structure was grown. Under pulsed optical excitation at room temperature, lasing was obtained at a wavelength of [lambda][similar to]670 nm, with a threshold power density comparable to that observed from similar structures prepared using AlAs/AlGaAs DBRs.
