Abstract
Light sources with low coherece and high coupling efficiency are needed for certain types of fiber-optic interferometric sensors. By driving a 1.3-µm diode laser with picosecond electrical pulses, we have reduced its coherence length to 44 µm. Coupling with an efficiency of 38% into a single-mode fiber has been measured.
