Overview
The Luna passive component group, originally from General Photonics, is a selection of fiber-coupled passive components. Most are available with single-mode (SM) or polarization-maintaining (PM) fiber at 1550, 1310 or 1064 nm. The product group has been discontinued.
The group includes SM and PM couplers that split light at specified ratios, polarization beam combiners/splitters that combine or separate light of orthogonal polarization states, Faraday rotator mirrors that rotate reflected light by 90° to counter system polarization effects, in-line polarizers that transmit a single linear polarization, isolators that transmit light only in the forward direction, and 3-port circulators that separate light traveling in forward and reverse directions.
Pigtailed and NoTail versions
Most components are offered either pigtailed or as NoTail versions without external pigtails, which are convenient for laboratory use and storage. NoTail 1- and 2-port components contain almost no internal fiber, which suits applications that need a minimal optical path length. NoTail 3- and 4-port components carry mounting magnets for temporary placement on an optical table.
The components can be used as accessories for many instruments and modules, as well as in test setups and assemblies.
