LASER COMPONENTS DG now manufactures avalanche photodiodes with fiber pigtails. With a semiautomatic assembly unit, the fibers can be adjusted exactly to within a few µm and thus achieve output coupling efficiencies of almost 100%. The pigtailing technology is very flexible – almost any combination of APD and fiber can be implemented: all optical fibers with a core diameter of < 600 µm can be combined with our APDs in a TO-46 housing.
The advantages of fiber coupling are obvious: 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 disruptive signals with the help of an opaque fiber jacket; in industry, however, data is transmitted across very long distances via optical fibers.
Product portfolio: Initially, we offer our SAP-series Geiger-mode APDs and the particularly low-noise IAG-series InGaAs APDs on a standard basis. Hermetically sealed and with high mechanical durability, these APDs exceed the requirements of the Telcordia GR-468 standard.
The development of APDs according to customer specifications is inexpensive and possible at any time.
