Outline of Final Research Achievements

In this project, we sought to apply phased-array antenna technology, which is widely used in the microwave frequency range, to the optical wavelength range and implement it on the photonic integrated circuits to realize high-speed optical switching and scanning devices. We first extended our previously developed 1x8 optical phased array switches to multi-input configuration to realize a monolithically integrated InP 8x8 matrix switch. We then developed ultra-compact 8x8 matrix switch by using silicon photonics platform. Concurrently, we fabricated optical beam-steering chip using the phased array scheme and demonstrated one-dimensional beam scanning. The developed technologies should have diverse applications including optical communication and sensing.
