Abstract :
A four-port waveguide-type optical accessor, which is spliced with optical fibres by CO2, laser fusion, has been realised using high silica channel waveguides. The accessor shows excess loss of about 3 dB for both optical branching and mixing, together with low crosstalk of less than ¿65dB.
