We demonstrate two modified uni-traveling carrier photodiode (MUTC) structures that
incorporate a charge or “cliff” layer to attain high-saturation-current. MUTC1 achieved …

We demonstrate high current operation of an evanescently coupled Ge waveguide nip
photodetector grown on top of a Si rib waveguide. A 7.4 μm× 500 μm device was found to …

Excellent high-temperature performance (298–523 K) of the 4H-SiC npn bipolar
phototransistor detector (PTD) was explored. It was fabricated using the 4H-SiC epitaxial …

The linearity, the RF output power, and the bandwidth for pin photodiodes (PDs) and
modified uni-traveling carrier (MUTC) PDs are analyzed for a variation of bias voltage and …

We report a high-gain, low-noise-figure, and high-linearity analog photonic link. The link
combines a high-power and low-noise fiber laser, a Mach–Zehnder modulator, a high-gain …

We present an avalanche photodiode (APD) with high-speed, high-responsivity and high-
linearity operation to cope with higher order modulation format, such as pulse-amplitude …

We demonstrate photonic high-power MMW generation at subTHz (160 GHz) frequencies by
using ultrafast near-ballistic unitraveling carrier photodiodes (NBUTC-PD), which have a …

Linearity is a very important parameter to measure the performance of avalanche
photodiodes (APDs) under high input optical power. In this paper, the influence of the …

The third-order intermodulation distortions of InGaAs/InP modified uni-traveling carrier
photodiodes with a highly-doped p-type absorber are characterized. The third-order local …

This article presents a linearized microwave photonic link by means of two parallel Mach-
Zehnder modulators (MZMs) and a polarization beam combiner (PBC). The proposed link …
