The development of uni-traveling carrier photodiodes over the past 25 years is briefly reviewed and the key design parameters in their structure are discussed. Monte Carlo simulation run for minority electrons in a p-type InGaAs structure reveals how

We developed a thermo-optic effect based silica optical phased array (OPA) chip and evaluated its tunability of phases of lightwaves. The THz waves, whose phases are controlled by the OPA chip, are generated from four arrayed uni-travelling-carrier p

We developed a novel terahertz-wave detector fabricated on a SiC platform implementing an InP/InGaAs Fermi-level managed barrier (FMB) diode. The FMB diode epi-layers were transferred on a SiC substrate, and a waveguide coupler and filters were monol

A zero-biased Fermi-level managed barrier diode that was packaged with a WR-3 rectangular-waveguide-input port was developed. For direct (square-law) detection operations, the fabricated module exhibited a 3 dB bandwidth covering the whole WR-3 band.
