| Outline of Final Research Achievements |
The purpose of this research is to develop the compact and high sensitivity biosensors using Si photonics. Differential Si ring resonators and photonic crystal (PhC) resonators were investigated. For the differential ring resonators, the method to obtain a constant sensitivity was proposed and the practical sensitivit of 0.5 ng/ml was achieved for the prostate specific antigen. Concerning the PhC resonators, it was found that the cavity type resonator has the superior sensitivty than defect type. Spot size converter, which enhances the coupling constant more than 30 times than previous, was developed. Thermal change mechanism for the resonance wavelength was studied and it was revealed that the intrinsic refractive index change is dominant than that of mechanical deformation.
