glass is reported in this paper.The mode field distributed curves of strip waveguide were measured by near-field method.It is shown that dismatch loss of coupling between fibre and waveguide is 0.54 dB
the transmission loss of the waveguide is 0.21 dB/cm. And 1×2 and 1×4 single mode waveguide splitter used for large capacity coherent optical communication were produced.
