The fabricated 1.55µm high power superluminescent light emitting diodes (SLEDs) with 115mW maximum output power and 3dB bandwidth of 50nm, using active multi-mode interferometer (MMI), showed high coupling efficiency of 66% into single-mode fiber, which resulted in maximum fiber-coupled power of 77mW.
