Summary form only given. Long wavelength VCSELs are crucial for single mode silica-fiber data transmission with link lengths of several km and high data rates beyond several Gbits/s. This simple data link will avoid modal dispersion and noise in existing multi-mode LAN systems. High performance GaInAs-GaAs edge emitting lasers have been demonstrated. Recently, our group and Sato of Ricoh independently demonstrated low threshold current density operations of highly strained GaInAs-GaAs QW lasers emitting at nearly 1.2 /spl mu/m wavelength. We achieved a record characteristic temperature as high as 150 K. We also realized uncooled CW operations and carried out single mode fiber data transmission. In this paper, we review our latest results on 1.2 /spl mu/m GaInAs-GaAs lasers and discuss their applicability to data coms.
