Optical Light Sources

What Is an Optical Light Source

An optical light source is a calibrated device that emits optical power at one or more defined wavelengths. The emitted light is used as a reference signal when testing fiber links, optical components, and system performance.

Depending on the application, optical light sources may produce single-wavelength, multi-wavelength, tunable, or broadband output. Output stability, wavelength accuracy, and spectral purity are critical factors that directly affect measurement accuracy.

Optical Light Source Technologies

Different optical light source technologies are used depending on wavelength coverage, output power, and application requirements.

Laser-Based Optical Light Sources

Laser-based light sources generate coherent optical output at specific wavelengths. They provide high spectral purity, narrow linewidth, and stable output power.

These sources are widely used in DWDM and CWDM testing, wavelength accuracy verification, and optical component characterization where precise wavelength control is required.

Broadband Optical Light Sources

Broadband light sources emit optical energy across a wide wavelength range. They are commonly used for spectral response testing, insertion loss measurements, and characterization of passive optical components.

Broadband sources are essential for evaluating filters, multiplexers, and wavelength-dependent loss characteristics.

Tunable Optical Light Sources

Tunable light sources allow continuous adjustment of output wavelength across a defined range. They are critical for advanced testing applications such as DWDM channel validation, passband characterization, and photonic device research.

These sources provide flexibility for sweeping wavelengths and analyzing component behavior across the optical spectrum.

Types of Optical Light Sources We Offer

Single-Wavelength Light Sources

Single-wavelength sources provide stable output at fixed wavelengths commonly used in fiber-optic systems. They are widely used for basic fiber testing, link verification, and calibration workflows.

Multi-Wavelength Light Sources

Multi-wavelength sources generate output at several predefined wavelengths. They are commonly used in CWDM testing and system verification where multiple channels must be evaluated efficiently.

Tunable Laser Sources

Tunable laser sources are used in high-precision laboratory and production environments. They support wavelength sweeping, channel alignment, and detailed optical component analysis.

Stabilized Optical Sources

Stabilized optical sources are designed for long-term output stability and repeatability. They are often used as reference sources in calibration environments and automated test systems.

Key Technical Parameters Engineers Evaluate

When selecting optical light sources, engineers consider several critical performance parameters:

• Wavelength range and accuracy
• Output power level and stability
• Spectral linewidth and coherence
• Output polarization characteristics
