摘要：
An optical 90 degrees hybrids based on silicon-on-insulator (SOI) 4x4 MMI couplers have been fabricated in 340nm top silicon using E-Beam technology. Below 2.2 degrees phase deviation of the hybrids for the across C-band of TE mode have been simulated, which is well satisfied with the typical systems requirements. The measured optical transmission powers from port to port show that the devices function well as a 6dB power divider with excess loss around 1dB at wavelength lambda=1550nm for TE mode. The measured transmission spectra of the 4x4 MMI coupler are seriously affected by the FP resonance noise, which bring in error in phase deviation testing.
