Abstract

We report a compact transmitter with 0.4 W output optical modulation amplitude at 1 Gb/s using a twin-contact directly modulated laser with a -100 mA applied current swing and a 2 A constant bias current. Bit-error-ratio measurements confirm high signal quality for optical wireless communication applications.
