【Abstract】 A low-loss glass-based buried multimode waveguide is fabricated by using the field-assisted Ag+-Na+ ion-exchange technique,and multimode optical power splitters are fabricated and demonstrated.The loss and the off-center impact of the multimode waveguides and optical power splitters are measured and analyzed in details.The measured loss of the multimode waveguides are lower than 0.1 dB/cm,and the additional loss of the multimode optical power splitters are lower than 1.3 dB.更多还原
