Abstract :
The authors present 1.3 μm light-emission-and-detection (LEAD) diodes fabricated by semi-insulating MOVPE growth and C2H6 dry-etching processes. As a laser, this LEAD diode operates with low threshold and high power. Aging test results confirm ifs long-term stability of up to 4500 h. As a detector, a high sensitivity of 0.42 A/W and a polarisation insensitivity of less than 0.3 dB were achieved by using facet coating and a bulk active layer. The capacitance was effectively reduced to 0.6 pF by introducing a semi-insulating current-blocking structure
