InGaAsP/InP DH LEDs with planar buried ridge structure (PBRS) for single mode optical fiber communication system have been investigated.The design for materials and device is briefly descrbed. Heterostruc-ture crystals were grown by two-step LPE technology. The LED has a tilted back facet to suppress laser oscillation and a planar buried ridge stripe active region. The device was coupled with single mode fiber using laser welding and metallized fiber coupling and packaging technology. The launched power in single mode fiber was 35 microwatts. This result is reported for the first time in China.The bandwidth of the LED was 195MHz. In 140Mb/s single mode fiber transmission experiments, transmission distance without repeater was more than 20km.
