Investigations of laser array for parallel optical data link applications

Abstract
Very low threshold (Ith∼1 mA) lasers emitting near 1.3 μm have been fabricated using multiquantum‐well active region, short cavity length, and high reflectivity facet coatings. A laser‐array transmitter utilizing these lasers can be operated without prebias and has negligible timing skew for 1 Gb/s operation. No crosstalk is observed when adjacent elements of the laser array are modulated.
