| Outline of Final Research Achievements |
We aimed to develop an imaging method using a large-scale optical phased array integrated on a semiconductor chip. First, an optical phased array with 128 thermo-optic phase controllers integrated on a silicon chip was designed and fabricated, and ghost imaging was successfully demonstrated. In addition, by connecting it to a multimode fiber, a high-resolution two-dimensional imaging function was demonstrated. Furthermore, we proposed and fabricated a non-redundant optical phased array and achieved more than 19,000 resolvable points. For high-speed applications, we designed and fabricated carrier-injection-based device on InP and demonstrated nanosecond-order response time.
