Abstract :
A technique has been developed for coupling multimode fiber to ridge waveguides on a substrate. It consists of D-fiber and polymer waveguides. Fabrication techniques for each are presented. Average insertion losses as low as 1.5 dB for coupling multimode optical fiber to 6.0-cm-long waveguides were measured. It is noted that this new coupling technique has great potential for passive alignment of optical fiber to ridge waveguides
