Abstract

Optical and electrical performance of a high power semiconductor laser transmitter (HPST) and of the related driver electronics are presented. Stable single-lobed operation of the HPST is accomplished by retroreflection of one lobe of the dual-lobed far field using a GRIN lens and stripe mirror. The envisaged peak-power output power of 1 W is achieved and 120 Mbit/s data transmission applying QPPM is demonstrated. Preliminary results after 2400 h of a lifetest performed on a laser array without a stripe mirror yield a bias current increase of about 2.1 x 10 exp -5/h and an efficiency decrease of 1 x 10 exp -5 hr.
