Distributed Feedback (DFB) – Volume Bragg Grating (VBG) – Narrow Linewidth

Distributed Feedback (DFB) Lasers

What are Wavelength-Stabilized Laser Diodes?

Wavelength-stabilized laser diodes are a type of laser diode that maintains a stable output wavelength over time. This is achieved by incorporating a wavelength-selective element into the laser diode, which ensures that the output wavelength does not drift due to changes in temperature or drive current.

Learn More About Wavelength-Stabilized Laser Diodes

Wavelength-stabilized laser diodes are designed to provide a stable, narrow linewidth output. This is particularly important in applications where precise control of the output wavelength is required. The wavelength-selective element in the laser diode, often a diffraction grating (distributed feedback – DFB) or a volume Bragg grating (VBG), reflects only a specific wavelength back into the laser’s active region, stabilizing the output wavelength.

    • Distributed Feedback (DFB) Laser Diodes operate with a periodically structured element or diffraction grating in the device’s active region. This structure provides optical feedback for the laser, ensuring its operation on a single longitudinal mode, which results in a narrow linewidth. Known for their high wavelength stability, DFB laser diodes are widely used in applications requiring high spectral purity and stability.
    • Volume Bragg Grating (VBG) Laser Diodes use a Bragg grating to achieve high spectral purity and wavelength stabilization. Integrating a VBG into a laser diode introduces additional optical feedback, compelling the diode laser to emit light within the narrow optical bandwidth determined by the VBG.

One of the main benefits of wavelength-stabilized laser diodes is their high spectral purity. Because the output wavelength is stabilized, these devices can deliver a narrow linewidth output, essential in applications such as spectroscopy and telecommunications.

Another advantage of wavelength-stabilized laser diodes is their stability over time. Unlike non-stabilized laser diodes, which can exhibit wavelength drift due to temperature or drive current changes, wavelength-stabilized laser diodes maintain a constant output wavelength. This makes them ideal for applications that require long-term stability.

Wavelength-Stabilized Laser Diode Applications

Wavelength-stabilized laser diodes are used in a wide range of applications. Their high spectral purity and stability make them ideal for spectroscopy applications, where a stable, narrow linewidth light source is required to measure the absorption or emission spectra of different materials accurately. They are also used in telecommunications, where their stable output wavelength allows for precise control of the transmitted signal. In addition, wavelength-stabilized laser diodes are used in sensing applications, such as gas sensing and environmental monitoring, where the ability to measure the absorption of light at specific wavelengths accurately is crucial.

    • Telecommunications: Wavelength-stabilized lasers are used in fiber-optic communication systems where the wavelength of the laser needs to remain stable to minimize the effects of fiber dispersion.
    • Spectroscopy: These lasers are used in precision spectroscopy, including gas sensing and molecular spectroscopy, where the precise detection and measurement of various gases or molecules are required.
    • Medical Diagnostics: In the medical field, these lasers are used for diagnostic purposes, serving as pump lasers for non-linear frequency conversion (second harmonic generation) to pump solid-state fs-laser devices.
    • Research & Biophotonics: They are used in research applications such as atom/ion cooling, Bose–Einstein condensates, atom interferometry, quantum memory, and molecular spectroscopy. In biophotonics, they are used for applications like Raman spectroscopy, confocal microscopy, interferometry, bioinstrumentation, and cytometry.
    • High-Energy Laser Systems: In defense and aerospace industries, these lasers are used in high-energy laser (HEL) systems, where pumping at specific wavelengths is crucial for suppressing nonlinear effects.
