Microwave photonic radiators provide wide bandwidths and high powers at mm-wave frequencies that can be utilized in extremely high throughput wireless communications, and high resolution millimeter wave imaging systems where their rugged, compact designs enable integration into large scale millimeter wave phased arrays. This work presents the design, implementation and measurement of a millimeter...
We propose a novel 60-GHz compact antenna module integrated with photodiode. The module is actually designed and fabricated, and it is successfully demonstrated that the antenna beams of 1×8 and 2×4 arrayed modules can be remotely controlled by tuning wavelength of 60-GHz RoF signals.
We present here photonics-based field visualization systems for the millimeter-waves and THz waves. Synchronized coherent measurement system reveals several unique phenomena such as wavefront conversion by a metal hole array. Asynchronized measurement system enables us to visualize the amplitude and relative phase distribution of electromagnetic waves emitted from on-chip antenna devices in which...
