摘要: Two distinctly different integrated optical polarisers have been made with multilayer claddings and titanium indiffused lithium niobate waveguides, transmitting both TE TM polarisations. The device used on the crystal surface obtaining (20.9±0.3) dB/cm extinction ratio. polariser similar a vertical wall fabricated by ion-beam milling adjacent to waveguide, (17±3) dB
