Abstract

InP generic processes allow monolithic integration of sources, passive elements and detectors on a common p-n doped layerstack. The passive loss can be greatly reduced by formation of local p-n junctions by means of Zn-Diffusion or regrowth. The attainable loss is experimentally derived from spiral ring resonators, coupled to a waveguide via multimode interference. By folding the ring into a spiral we obtain circumferences up to 73 mm, with a footprint of 2.4 mm x 3.6 mm. We measure a quality factor of 1.2 million and extinction ratio of 9.7 dB, implying a loss below 0.4 dB/cm
