Abstract
Passive polarization mode splitters at λ= 1.55 ${\mu}{\textrm}{m}$ were designed and fabricated based on Ti:x-cut LiNbO$_3$ single-mode optical waveguide and two-mode interference theory. The splitting ratio with waveguide width 8 ${\mu}{\textrm}{m}$, branching angle 0.55$^{\circ}$ and interfering length 470 ${\mu}{\textrm}{m}$ showed 16.18 dB, 21.25 dB for TE and TM input polarization modes, respectively. Polarization cross-talk of -16.28 dB and -21.28 dB for TE and TM modes was achieved. Total insertion losses of 2.24 dB/cm (TE) and 2.41 dB/cm (TM) were also measured. The devices operated nearly wavelength independently over a range or 30 nm.
