Description

The Distributed Feedback Laser (DFB) from DAYY Photonics Corporation is a cutting-edge optical solution designed to meet the demanding needs of modern telecommunications and spectroscopy applications. This product family offers a broad selection of wavelengths, ranging from 1530nm to 1610nm, ensuring comprehensive coverage of the ITU grid for Dense Wavelength Division Multiplexing (DWDM) systems. The DFB laser module is particularly well-suited for gas detection applications, including tunable diode laser spectroscopy and cavity ring down spectroscopy, thanks to its precise wavelength control and high output power.

Each DFB laser is crafted with a high-performance, multi-quantum well (MQW) distributed-feedback laser chip, ensuring exceptional reliability and performance. The laser's center wavelength tolerance is maintained at CW +/- 0.2nm, with typical linewidths (FWHM) ranging from 1-3MHz. This precision makes it an ideal choice for applications requiring high spectral purity and stability. The laser module is available with a variety of light output options, including FC/APC connectors, with optional FC/PC or SMA configurations.

DAYY Photonics' DFB lasers are housed in industry-standard 14-pin butterfly packages or TO-Can packages, both of which are hermetically sealed to protect the internal components. These packages include a built-in thermoelectric cooler, thermistor, monitor diode, and integrated isolator, ensuring optimal performance and longevity. The product family is compliant with Telcordia GR-468 standards and adheres to RoHS/Reach regulations, underscoring its commitment to quality and environmental responsibility.
