The optical disk storage density is basically dependent on the reading laser wavelength because of the diffraction-limited resolution of the spot on the disk surface. Optical disk storage density is currently about 10 times that of magnetic disks. To keep that advantage, it is important to develop a shorter wavelength microlaser small enough to be mounted on optical disk pick-ups. The wavelength of conventional III–V visible diode lasers is limited to around 600 nm.
