Overview of the ASE Light Source (1.0 µm)

The ASE Light Source (1.0 µm) is a broadband emission system engineered for laboratory testing, fiber-optic evaluation and calibration workflows. Its low-coherence output minimizes interference artifacts, making it suitable for metrology, imaging and optical component assessment. Stable spectral performance and durable internal construction ensure consistent results in demanding environments.

Working Principle

An ASE source emits amplified spontaneous emission without resonant optical feedback, resulting in smooth broadband output. The 1.0 µm variant uses doped fiber amplification, feedback-suppression and thermal management to maintain low relative intensity noise, uniform spectral distribution and dependable power stability for extended duty cycles.

Key Features

• Broadband spectral output ideal for component analysis and imaging
• Low-coherence operation minimizes interference and speckle artifacts
• Stable long-term output with minimal drift
• Fiber-based construction for mechanical robustness
• Compact module or benchtop form factor
• Engineered for long operational life in lab and industrial setups

Design Characteristics

The internal design includes pump diodes, optimized gain fiber, feedback-suppressed optical paths, temperature regulation, integrated monitoring circuits and standard digital interfaces. These elements ensure stable spectral behavior and reduce maintenance overhead.

Applications

• Fiber-optic component testing (FBGs, couplers, WDMs)
• Laboratory calibration and measurement
• Interferometry and imaging system validation
• Optical communication research and loss analysis
• Material studies and spectral reference illumination
• Integrated photonics research and testing
