Abstract :
We evaluated connectivity between a Vertical Cavity Surface Emitting Laser (VCSEL) and a multimode optical waveguide. It is important to evaluate Far Field Pattern (FFP) of VCSEL. FFP is different depending on the VCSEL maker. Tolerance curve of Graded Index-Multi Mode Fiber (GI-MMF) and GI-core polymer waveguide under shifted VCSEL from center differed. We estimate the difference is depending on material and process. GI-core polymer waveguide makes scattering in optical waveguide.
