Abstract (in Japanese) (See Japanese page) 
(in English) We propose a structual optimization method based on a genetic alogorithm (GA) which is combined
a real coded GA and μGA to realize a weakly guided multimode interference(MMI). The proposed method was
applied to optical 90 ◦ -Hybrids employing silica-based 4 × 4 MMI couplers with operation across the C-band. The
optimized result showed an imbalance of less than 0.23 dB, an excess loss of less than 1.21 dB over the wavelength
range. than conventinal methods.
