摘要：

The letter reports the fabrication and performance of integrated-optic 64 x 64 and 144 x 144 star couplers based on the high-silica planar lightwave circuit (PLC) technology. The star couplers exhibit low insertion loss (average excess loss alpha = 1.66 dB for 64 x 64 and alpha = 2.02 dB for 144 x 144, respectively) and good splitting uniformity (standard deviation sigma = 0.92 dB for 64 x 64 and sigma = 1.47 dB for 144 x 144, respectively) at 1.55-mu-m.
