Abstract:
A method of manufacturing a collimating assembly comprises steps of:preparing a GRIN lens subassembly employing a sleeve forming a first stepped mating end; preparing a collimator pigtail subassembly employing a bushing forming a second stepped mating end; fitting the GRIN lens subassembly and the collimator pigtail subassembly together, forming a junction zone therebetween, wherein the junction zone is defined as that area where the first and second stepped mating ends of the sleeve and the bushing overlap each other, and the junction zone includes an interspace defined between the sleeve and the bushing; applying adhesive into the interspace of the junction zone between the GRIN lens subassembly and the collimator pigtail subassembly; and baking the junction zone to cure the epoxy therein until the epoxy spreads uniformly over the junction zone due to the so-called capillarity phenomenon.
