Abstract

In this work, we fabricated a few mode S-shape waveguide with a length of 20 cm by photolithography, the S-shape waveguide is designed with the minimum bending radius of 8 mm and the maximum bending radius of 13.7 mm. The waveguide core size is 15 μm × 10 μm, and the core pitch is 250 μm. The transmission loss of the waveguide is 0.22 dB/cm at 1310 nm and 0.64 dB/cm at 1550 nm, received by a multimode fiber. While, when the output is received with a single mode fiber, the corresponding values become 0.27 dB/cm at 1310 nm and 0.71 dB/cm at 1550 nm. The crosstalk of the waveguide is lower than -40 dB at 1310 nm.
