Abstract :
Thin-film polarisers using a dielectric buffer layer and a metallic overlay on Ti:LiNbO3 channel waveguides for ¿ = 1.3 ¿m have been designed and fabricated. The TM mode extinction ratio better than 35 dB and negligible TE mode excess losses have been measured with Si3N4/Al polarisers 2 mm long.
