“…Since this ratio is a material property, for a given electric field, efforts to improve the APD performance have focused on optimizing the electric field profile and characterizing new materials. Recently, lower multiplication noise and higher gainbandwidth products have been achieved by sub micrometer scaling of the thickness of the multiplication region [4][5][6][7][8][9][10][11][12]. This is in direct contrast to what would have been predicted by the local-field model and is due to the nonlocal nature of impact ionization, which can be neglected if the thickness of the multiplication region is much greater than the "dead length", the distance over which carriers gain sufficient energy to impact ionize.…”

Abstract-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 homojunction avalanche photodiode in the wide range of multiplication region width. Also in our calculations the effects of dead space has been considered. Our analyses based on the history dependent multiplication theory (HDMT) and width independent ionization coefficient.

“…Lenox et al [11] measured the frequency response of a pair of similar, separate absorption, charge and multiplication APDs with In Al As multiplication regions of length m and m. We have fitted their measured values of gain-bandwidth product to (1) to obtain an effective value of mean carrier velocity for each device. was calculated using the expression of Kuvås and Lee [8], valid for large values of gain and conveniently independent of carrier velocities, using values for the ionization coefficients ratio taken from the work of Watanabe et al [12].…”

“…Extremely high BWE values are achieved using Schottky, p-type-intrinsic-n-type (p-i-n), and an avalanche type of RCE-PDs, which could not be reached with conventional VPD structures. 100-GHz bandwidth [6] and 25-GHz BWE [7] for Schottky, 46-GHz BWE [8] for p-i-n, 35-GHz low-gain bandwidth, [9] and 17-GHz BWE [10] for avalanche type of RCE-PDs are the record performances reported to date.…”

Abstract-High-speed Schottky photodiodes suffer from low efficiency mainly due to the thin absorption layers and the semitransparent Schottky-contact metals. We have designed, fabricated and characterized high-speed and high-efficiency AlGaAs-GaAs-based Schottky photodiodes using transparent indium-tin-oxide Schottky contact material and resonant cavity enhanced detector structure. The measured devices displayed resonance peaks around 820 nm with 75% maximum peak efficiency and an experimental setup limited temporal response of 11 ps pulsewidth. The resulting 45-GHz bandwidth-efficiency product obtained from these devices corresponds to the best performance reported to date for vertically illuminated Schottky photodiodes.
