Abstract

A 2-bit polymer waveguide delay device composed of right-angle junctions, Mach–Zehnder thermo-optic switches and bending polymer waveguides is demonstrated. The four path device and Mach–Zehnder thermo-optic switch are fabricated using direct ultraviolet photolithography process. The fabrication procedures are demonstrated. The loss of bending waveguides, right-angle X junctions and Mach–Zehnder thermo-optic switches is calculated and analyzed. The near-infrared field guided-mode patterns of the device are obtained. Time delays of the 2-bit device are measured to be 0, 121.1, 242.3, and 365.7 ps.
