10-Gb/s data transmission experiments over polymeric waveguides with 850-nm wavelength multimode VCSEL array

A practical transmitter module was demonstrated, using a metal optical bench (MOB) and a tapered polymeric waveguide. The transmitter module was prepared for optical printed circuit board, which consists of the MOB, the driver chips, the vertical-cavity surface-emitting laser (VCSEL), and a tapered polymeric waveguide. We report a 10-Gb/s 2/sup 23/-1 pseudorandom bit sequence nonreturn-to-zero of data transmission from VCSEL to a multimode fiber block through a tapered polymeric waveguide. The tapered polymeric waveguide is fabricated with a large core size (100×60 μm²) by means of a hot embossing technique. The propagation loss of a tapered polymeric waveguide was approximately 0.1 dB/cm at 850 nm.
