“…The more general cases which may include dead space and/or more physical assumption on the drift velocities can be addressed in a similar way. We begin by proposing that for sufficiently large , (15) and (16) where and are spatial functions to be determined later, and is an exponential temporal rate.

“…In addition, the statistics of the impulse response function for the dead-space multiplication model, for which the ionizations process has a nonlocalized nature, have also been studied [21]. Many of the techniques used to calculate the second order statistics of the impulse response in conventional APD's require intensive computations [16], [21] and typically involve solving coupled integral or differential equations in multiple variables. Recently, Bandyopadhyay et al [22] proposed a computationally simple approach for calculating the mean impulse response function.…”

A new approach for characterizing the avalanchebuildup-time-limited bandwidth of avalanche photodiodes (APD's) is introduced which relies on the direct knowledge of the statistics of the random response time. The random response time is the actual duration of the APD's finite buildup-limited random impulse response function. A theory is developed characterizing the probability distribution function (PDF) of the random response time. Recurrence equations are derived and numerically solved to yield the PDF of the random response time. The PDF is then used to compute the mean and the standard deviation of the bandwidth. The dependence of the mean and the standard deviation of the bandwidth on the APD mean gain and the ionization coefficient ratio is investigated. Exact asymptotics of the tail of the PDF of the response time are also developed to aid the computation efficiency. The technique can be readily applied to multiplication models which incorporate dead space and can be extended to cases for which the carrier ionization coefficient is position dependent.

“…As such, we would expect that reducing the width of the multiplication region to reduce the buildup time. On the other hand, a rich literature also exists for the nonlocal ionization case (Emmons, 1967;Kuvås and Lee, 1970;Kahraman et al, 1992;Saleh et al, 1990;Plimmer et al, 2001;Ong et al, 2003;Tan et al, 2003;Hayat and Dong, 2000;, which suits thin APD as well. Nonetheless, the behavior of the buildup time is more complex than it appears.…”
