Using GaAs-on-InP heteroepitaxial technology, a 1.3 mum OEIC transmitt
er combining a BRS laser with two GaAs metal-semiconductor field-effec
t-transistors has been fabricated. The device design, fabrication proc
essing and performance are described. 8 Gbit/s NRZ direct modulation i
s demonstrated. This is the highest bit rate ever reported for GaInAsP
laser GaAs-on-InP transistor circuits.
