Home / Selection Guide for Low-Loss Avionics-Grade DFB Distributed Feedback Lasers
📦 For purchasing, use the RP Photonics Buyer's Guide for distributed feedback lasers. It provides an expert-curated supplier directory, buyer-focused technical background information, and structured selection criteria to support professional procurement decisions. Their key features relative to other semiconductor lasers are their single longitudinal mode (single frequency) emission profile, their high stability and their wavelength tunability. Clicking the "Choose Item" drop-down opens a list containing all of the in-stock lasers around the desired center wavelength. LIV and spectral measurements can be downloaded by clicking the red icon corresponding to each serial number. Selecting the right Distributed Feedback (DFB) laser is a critical step for ensuring superior performance in fiber-optic communication, gas sensing, spectroscopy, and next-generation photonic system design. Covering NIR to LWIR wavelengths (750nm–17µm), these lasers feature integrated DFB gratings and TEC cooling for robust.
