High–speed, high–power photodiodes play a key role in wireless communication systems for the generation of millimeter wave (MMW) and terahertz (THz) waves based on photonics–based techniques. Uni–traveling–photodiode (UTC–PD) is an excellent candidate, not only meeting the above...
The fast development of mid-wave infrared photonics has increased the demand for high-performance photodetectors that operate in this spectral range. However, the signal-to-noise ratio, regarded as a primary figure of merit for mid-wave infrared detectio

range of applications as theα/βratio is fairly large over a wide range of electric fields5and this can yield fairly low excess noise. Silicon, however, has an indirect bandgap energy (Eg) of 1.1 eV, limiting it to the detection of photons below ~1000 nm. To get sufficient ...
