2.5 Gbit/s data link using oxidized sub mA threshold VCSELs

Intensity modulated laterally oxidized InGaAs strained QW vertical cavity surface emitting lasers (VCSELs) with threshold current as low as 0.45 mA are investigated as light source for optical interconnection. Data transmission at 2.5 Gbit/s with a BER of less than 10/sup -11/ is reported for transmission over 500 m of graded index multi-mode fiber.
