Abstract :
Low-loss Y-branch 3 dB power dividers in Ti:LiNbO3 have been designed and tested. The symmetric output arms consist of S-bends. Numerous Y-branches were made exhibiting <0.25 dB excess loss for both the TE and TM polarisations. Histograms of the splitting ratio are also included, and demonstrate the excellent splitting ratios achieved.
