Avalanche Photodiodes and Silicon Photomultipliers of Non-Planar Designs
Conventional designs of an avalanche photodiode (APD) have been based on a planar p–n junction since the 1960s. APD developments have been driven by the necessity to provide a uniform electric field over the active junction area and to prevent edge ...

Avalanche photodiodes with multiple multiplication layers for coherent detection
We demonstrate a novel avalanche photodiode (APD) design which fundamentally relaxes the trade-off between responsivity and saturation-current performance at receiver end in coherent system. Our triple In0.52Al0.48As based multiplication (M-) layers with

NUMERICAL ANALYSIS OF HOMOJUNCTION GALLIUM ARSENIDE AVALANCHE PHOTODIODES (GAAS-APDS)
In our earlier work we introduce a numerical analysis to investigate the excess noise and performance factor of double carrier multiplication homojunction avalanche photodiodes (APDs) considering the nonlocal nature of the ionization process. In this paper we investigate the gain, breakdown voltage and carrier injection breakdown probability of ...

Numerical simulation of neutron radiation effects in avalanche photodiodes
A new one-dimensional (1-D) device model developed for the simulation of neutron radiation effects in silicon avalanche photodiodes is described. The model uses a finite difference technique to solve the time-independent semiconductor equations across a ...

BER Performance of UWOC With APD Receiver in Wide Range Oceanic Turbulence
In this paper, the bit error rate (BER) performance of underwater wireless optical communication (UWOC) systems with on-off keying (OOK) modulation and an avalanche photodiode (APD) detector are analyzed in a wide range of oceanic turbulence environment,

Performance Recovery of Silicon-Avalanche- Photodiode Electron Detector by Low-Temperature Annealing
We report that the silicon avalanche photodiode (APD) for electron detection almost fully recovers from the damage caused by electron irradiation by annealing. With the electron irradiation at an energy of 8 keV, a prominent increase of the non-amplified

NUMERICAL ANALYSIS OF HOMOJUNCTION AVALANCHE PHOTODIODES (APDS)
In this paper we introduce a rigorous numerical analysis to investigate the characteristics of double carrier multiplication homojunction avalanche photodiodes (APDs) considering the nonlocal nature of the ionization process in the wide range of multiplication region width. Also in our calculations the effects of dead space has been considered.
