A new estimation method is proposed in order to clarify waveguide phase error factors. Using the proposed method, it is possible to analyze such factors as core size error and refractive index error, which cause optical phase error in waveguides. This method is applied to silica-based waveguides to estimate the waveguide phase error. This revealed an average core size error of 2.1/spl times/10/sup -3/ /spl mu/m and an average refractive index error of 1.9/spl times/10/sup -6/. Finally, based on… CONTINUE READING
