Applications

Application areas include wavelength-matched pumping of specialty fiber and solid-state lasers, fiber sensing and spectral analysis. Optical communication is another evaluation context, but compatibility with a particular transceiver or modulation architecture must be established for the complete system.

Integration considerations

For optical integration, review the specified spectral width and wavelength drift alongside the required wavelength band and thermal arrangement. The ceramic package does not by itself specify a fiber connector or fiber-coupled output. Confirm the package drawing, optical coupling, electrical connections and CW acceptance conditions when requesting a configuration for your assembly.
