Low threshold (380 /spl mu/A) and single transverse mode operation of 1.55-/spl mu/m BH vertical-cavity surface-emitting lasers

Summary form only given. We report high performance of 1.55-/spl mu/m. BH-VCSELs. A record threshold current as low as 380 /spl mu/A at 20/spl deg/C, single-mode operation up to the maximum output power, and an operating temperature as high as 60/spl deg/C are achieved.
