Abstract :
A four-channel monolithic laser/photodiode array with microcleaved inner facets has been developed. The laser array exhibits low threshold currents and high quantum efficiencies with good uniformity, owing to the use of a GRIN-SCH single quantum well structure as well as the improved microcleaved facet process.
