The on-chip avalanche photodiodes (APDs) are crucial component of a fully integrated photonics system. Specifically, III–V compound APD has become one of the main …
In 1982, Capasso and co-workers proposed the solid-state analogue of the photomultiplier tube, termed the staircase avalanche photodiode. Through a combination of compositional …
If a receiver system is circuit-noise limited, avalanche photodiodes can be beneficial, as their internal gain mechanism can lead to a higher system signal-to-noise ratio. However, the …
Accurate detection of weak optical signals is a key function for a wide range of applications. A key performance parameter is the receiver signal-to-noise ratio, which depends on the …
By utilizing the low-noise benefits of staircase avalanche photodiodes (APDs) and the high- field tolerance of conventional APDs, a “cascaded multiplier” device has been grown and …
We report AlInAsSb separate absorption, charge, and multiplication (SACM) avalanche photodiodes with a> 3-optical cutoff, operating at 240 K. Gain and dark current performance …
We report an nBn photodetector based on the AlInAsSb digital alloy materials system, which has the advantage of a near-zero valence band offset. These photodetectors have achieved …
We report Al_0. 3InAsSb/Al_0. 7InAsSb digital alloy n-barrier-n (nBn) photodetectors that operate in the 2-µm wavelength window. The Al_xIn_1-xAs_ySb_1-y digital alloy material …
