| Outline of Final Research Achievements |
In this project, we aimed to develop compact plasmonic devices based on metallic cavity structures to realize future ultra-dense photonic integrated circuits. First, we optimized the key device processes to fabricate our original capsule-shaped metallic-cavity structures. As a result, we have succeeded in substantially reducing the sidewall roughness to observe room-temperature lasing operation under optical pumping. We also designed and fabricated a novel device structure with an optimal current-blocking layer to achieve electrically pumped lasing at low temperature. Finally, we proposed and designed a novel cavity structure coupled to an optical waveguide, and succeeded in device fabrication.
