With the use of the lateral leakage of a shallowly etched rib waveguide, 1-mm-long TE/TM-pass polarizers with high extinction ratios of 28.72/24.03 dB are acquired. Because of the anisotropy associated with the lithium niobate, the lateral leakage of TE/TM polarization settings can happen along crystallographic z/y directions, correspondingly. Such TE/TM-pass polarizers could be integrated in identical wafer.We demonstrated an ultra-low-noise polarization-maintaining (PM) single-frequency fibre laser at 2 µm
