Optical Package Assembly
Author: Dr. Klaus Ohlsen
Abstract: Optical packages are assemblies comprising optical (lenses, prisms, apertures, filters etc.) and electronic components (LD, PD, amplifiers, controllers etc.). Applications can be found in communication technologies where optical signals are transformed into electrical signals and vice versa. In order to have a package working properly it is mandatory that the optical and electronic parts are aligned to each other with highest precision. The task becomes even more complex as, by design, these packages typically are actively tempered by thermo-electric coolers (TEC), which need to be integrated into the assembly as well. This technical paper describes typical process steps in the assembly of high-performance optical transceiver modules.
