In this paper, different single-mode Y-branch splitters are simulated based on symmetric Y-branch comprising different waveguides (straight, S-Bend Cosine, S-Bend Sine and S-Bend Arc waveguides) with a channel profile of proton-exchanged lithium niobate. Apart from the waveguides length of the two branches, all other parameters such as the width of the waveguides and separation of the two branches are considered fixed. The distance between the two output waveguides is 127μm (center-to-center), which is suitable for the connection with the fibers. For each structure, the excess loss of the splitter is checked, and according to the minimum loss, optimum length of waveguide is determined. Finally, an optimum single-mode Y-branch splitter is selected..

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
