LASER COMPONENTS Detector Group (LCDG) now manufactures avalanche photodiodes with fibre pigtails. With a semi-automatic assembly unit, the fibres can be adjusted precisely within a few microns and thus achieve coupling efficiencies of almost 100%. The pigtailing technology is very flexible - almost any combination of APD and fibre can be combined. All optical fibres with a core <Ø 600 µm can be coupled to our TO-46 housed APDs.
The advantages of fibre coupling are significant, for example; in medical technology or analytical measurement technology, it is not often ideal to have the detector close to the area of measurement; in photon-counting applications, it is possible to shield interference optical signals with the help of an opaque fibre jacket; in industry, data is transmitted across very long distances via optical fibres.
The Product Portfolio: initially, we offer our SAP-series Geiger-mode APDs and the particularly low-noise IAG-series InGaAs APDs as standard. Hermetically sealed and with high mechanical durability, these APDs exceed the requirements of the Telcordia GR-468 standard.
We can develop custom APD specifications as an inexpensive alternative.
