| Outline of Final Research Achievements |
We propose the SOI-PIN photodiodes. It is expected that the devices are operated at over 20 GHz by optimizing electrode spacing, receiving size and pad size. The devices are fabricated by foundry service. The devices were measured at the wavelength of 0.8 um region. The maximum bandwidth of 13 GHz was obtained at the electrode spacing of 0.6 um, receiving size of 20×20 um2 and pad size of 30×30 um2.
We proposed a design of waveguide type polarization splitter based on directional coupler which is advantageous in terms of size. It was confirmed by FDTD analysis that it can be realized by setting the combination of coupling length to 1: 2. Furthermore, we fabricated devises using foundry service and report results of measured polarization characteristics. From the result of the measurement, it was confirmed that this device was operating and an extinction ratio of 20 dB or more was obtained.
