Abstract

We propose a novel high-density and low-profile multi-fiber passive assembly technology to polymer waveguides. We developed a small-sized ferrule with a footprint of only 5 × 5 mm and a thickness of 0.5 mm. An embedded 12 v-groove silicon chip was employed as a receptacle, and we formed the facet of waveguides on the v-groove chip. The optical properties for the proposed structure were experimentally demonstrated. The propagation loss of the single mode waveguides was as small as 0.5 dB/cm for the wavelength of 1310 nm and the average connecting loss of 3.06 dB was obtained.
