We propose a novel design for low-loss wide-angle Y-branch structures, called truncated structural Y branch (TSYB), which is shown to have the lowest loss compared with some other proposed structures under wideangle conditions. The advantage of this design is that it does not require the implementat

## Abstract A lowβloss wideβangle Yβjunction with gradedβindex optical waveguides which can change the optical propagation direction, is proposed. The optical power is divided equally into two branching waveguides with a wide angle. Device performance is examined numerically by the finiteβdifferenc
A 1 β’ 4 polarization and wavelength independent optical power splitter is reported. This device is based on a novel wide-angle lowloss Y-junction structure which can give a theoretical TE junction excess loss of 0.26 dB at a branching angle of 16Β°. To the best of our knowledge, it is so far the lowe
