Design of a Low Loss and Large-Tolerance Optical Interface for Large-Area Optical Waveguides
circuit board using a step-out fabrication technique is proposed. In this paper, we simulated and compared our proposed structure to a typical straight core structure in order to investigate the misalignment tolerances and coupling excess losses.
Low-loss polymeric directional couplers and 8-inch large-area optical waveguides fabricated by laser-beam writing
Directional couplers and 8-inch large-area optical waveguides were successfully fabricated by a laser-beam writing technique. Their propagation losses were as low as those of waveguides patterned by a conventional photolithographic technique with a photomask.
10 Gb/s data transmission with TO-packaged multimode GaAs VCSELs over 1 m long polymer waveguides for optical backplane applications
Abstract TO-packaged GaAs vertical-cavity surface-emitting lasers (VCSELs) are being investigated for high-bit-rate data transmission over 103 cm of a 250×200 μm 2 core size polymer-based optical waveguide to be employed in optical backplanes. The bit-error rates for 5 and 10 Gb/s transmission over the waveguides incorporating 45° deflection mirrors are better than 10−12. For the first time, the measured bandwidth-length-product for a polymer-based optical backplane exceeds 10 GHz × m .
