Research Abstract

We developed the phase error measurement system where the optical coupling at each channel of an arrayed-waveguide grating could be made automatically. We created a program for revealing the refractive index change over the slab waveguide lens at the output ports by using the phase error distributions of individual channels measured with the system. We were able to reduce the intensity change due to CO2 laser irradiation to 0.3% by expanding the diameter of the CO2 laser light.
