Brief
The article experimentally presents a high erbium-doped amplified spontaneous emission (ASE) source utilizing a double-pass double-stage configuration with an optical circulator and two fiber loop mirrors to achieve a broad bandwidth and improved output power.
Summary
This paper experimentally demonstrates a high-power and broad-bandwidth Amplified Spontaneous Emission (ASE) source using a double-pass double-stage configuration that combines an optical circulator with two fiber loop mirrors (FLMs). The design utilizes highly erbium-doped fiber (4000ppm) to achieve an output power of over 0.79 dBm with a 3dB bandwidth of 85.3 nm spanning the C and L bands (1526-1611.3 nm). This compact ASE source is suitable for applications in fiber Bragg grating (FBG) sensors, fiber optical gyroscopes, and DWDM systems. Simulations suggest the potential for even wider bandwidth and higher output power.
