1.1-1.2 /spl mu/m multiple-wavelength vertical cavity surface emitting laser array with highly strained GaInAs/GaAs QWs on patterned substrate

We demonstrated a single-mode multiple wavelength VCSEL array with highly strained GaInAs/GaAs QWs on a patterned GaAs substrate in the new wavelength band of 1.1-1.2 /spl mu/m. The emission wavelength of a 16-channel array ranges from 1116 nm to 1154 nm. By using this technique, the wavelength span of the multi-wavelength GaInAs/GaAs VCSEL can be expanded and we can expect a wideband WDM-LAN using the VCSEL array.
