Abstract(in English) This paper presents a study of a polyimide inverted rib waveguide for single mode communication. With slab thickness fixed, inverted rib waveguide enables the controlling of confined optical field by means of only changing its transversal dimension (rib width). It gives high coupling efficiency as an SSC (SpotSize Converter) with optical fiber and also gives high light confinement for low radiation. Numerical results reveal that coupling loss less than 1dB, mode transition loss less than 0.1dB in the taper area can be achieved with a 4μm spot-sized fiber and strong confinement resulting in radiation loss as low as 0.007dB∿0.45dB. Also, misalignment coupling tolerance of 1.5μm is confirmed, which comes to easy alignment in optoelectronic systems implementation.
