Abstract: A low-loss 1 x 256 optical power splitter is designed and fabricated using silica-based planar lightwave circuit technology on a 6-in. quartz substrate. The measured results show that the insertion loss, uniformity, and wavelength-dependence loss (WDL) of a 1 x 256 splitter are <26.2, 1.97, and 1.83 dB, respectively, in the wavelength range from 1.26 to 1.63 mu m. The insertion loss, uniformity, and WDL of a 1 x 256 splitter are <25.62, 1.33, and 1.03 dB, respectively, in the normal communication wavelength range from 1.31 to 1.55 mu m. The polarization dependence loss is <0.16 dB in the wavelengths of 1.31 and 1.55 mu m. (C) 2021 Society of Photo-Optical Instrumentation Engineers (SPIE)
