We demonstrated a single-mode multiple wavelength VCSEL array with highly strained GaInAs/GaAs QWs on a patterned GaAs substrate in a new wavelength band of 1.1-1.2 μm. The emission wavelength of a 4-channel array ranges from 1137 nm to 1144 nm. We carried out data transmission experiment through a 5 km single mode fiber with 2.5 Gbps/channel. The total throughput reaches 10 Gbps. This novel WDM source would be a good candidate for WDM-LAN beyond 10 Gbps. In addition, we show a potential extension of the wavelength span for multiple wavelength VCSEL arrays by optimizing the pattern shape of a substrate.
