| Outline of Final Research Achievements |
The purpose of this research is to realize optical memories based on semiconductor ring lasers having nonreciprocal function. Toward this goal, we have done (1) Characterization of bend optical waveguides, (2) Estimation of optical isolation for optical memories, and (3) Design, fabrication, and characterization of passive semiconductor optical isolators.
Owing to the above experiments and simulations, it was found that we can realize the bend optical waveguides having its radius of 30μm. Also we theoretically estimated optical isolation for optical memories based on semiconductor ring lasers, and experimentally demonstrated the optical isolation. We are fabricating optical directional coupler to connect / separate the input/output waveguides and the ring cavity for optical memories having the radius of 30 μm.
