Paper Abstract

An imprinted polymeric wavelength-independent coupler (WINC), which is one of the core components used in optical fiber communications and fiber-to-the-home systems, was designed with a beam propagation method. Its designed structure has the form of the Mach-Zehnder interferometer. The polymer core size of the WINC was optimized at 8×8  μm using an imprinting technique, the hot embossing process. Optical properties of the polymeric WINC were evaluated by measuring its insertion loss and transmission spectrum. The insertion loss values for channels 1 and 2 were 3.5 and 4.2 dB, respectively, and the transmission spectrum was flat over a range of 1260 to 1640 nm.
