High-power (>80 mW) and high-efficiency (>30%) 1.3 µm super-luminescent diodes
High-power (>80 mW) and high-efficiency (>30%) 1.3 µm super-luminescent diodes (SLDs) are reported. The use of a longer cavity allows the building of an SLD the power and efficiency of which exceed those of a laser diode (LD). The cavity length dependence of power, efficiency and bandwidth, and the power and efficiency comparison with an LD, are examined.
