Voxtel APDs Introduction to Avalanche Photodiodes Voxtel's avalanche Photodiodes (APDs) offer superior response and linear-mode, low-light-level detection capabilities that conventional telecommunications APDs and Geiger-mode APDs can't offer. Customers with applications that are presently served by NIR Photodiodes or low-gain telecom APDs will often prefer the Deschutes FSI or Deschutes BSI APDs and Photoreceivers for their modest price and low-noise performance at gains up to M = 25.

8 A variety of high-performance and low-light-level applications are best served by our Siletz line of high-gain, high-responsivity products. Voxtel's single-element devices are available as bare die, on submounts (for our backside-illuminated prod- ucts), in hermetic packages, and integrated into Photoreceivers , with a variety of options for packaging and optical input. Voxtel's APD Product Series 7. Voxtel produces a number of high-performance InGaAs APDs, and each is best suited for a particular range of applications. This guide discusses the differences between Voxtel's products and related products for NIR. detection, as well as the differences among Voxtel's product lines. Silicon vs. Voxtel's InGaAs APDs Voxtel's APDs are replacing silicon APDs in many applications. Silicon APDs are typically used for the 300 . 1100 nm spectral band, while InGaAs APDs normally cover the 900 1700 nm band. Their response overlaps in the 900 1100 nm spectral region, which includes the ubiquitous 1064 nm Nd:YAG solid-state laser line that is used in many systems for range finding and target designation.

9 Voxtel's InGaAs APDs are often an attractive alternative to silicon APDs in designing new systems where a fast signal rise time is required, and have served many users of silicon APDs in migrating to eye-safe systems at 1550 nm while maintaining backwards compatibility with legacy 1064 nm illuminators. However, the detector specifications can be considerably different for the two types of APDs, so depending on the application, it may not be feasible to use an InGaAs APD as a drop-in-replacement for legacy systems using a silicon APD. Voxtel's InGaAs APDs are often the best choice for low-light-level and/or high-bandwidth applications, though understanding the differences between our detectors is important in order to choose the right Voxtel APD for a particular application.

10 Choosing a Voxtel APD: Three product lines Initial considerations: FSI vs. BSI spectral response and mechanical differences Voxtel sells three InGaAs APD product lines: the Deschutes FSI , Deschutes BSI , and Siletz series. The Deschutes FSI series of APDs are front-side-illuminated (FSI), while the Deschutes BSI , and Siletz series APDs are back-side-illuminated (BSI). The most important difference between FSI and BSI configuration is that the FSI APDs are able to absorb wavelengths below 950 nm, but for applications at 950 nm and above, the BSI. APDs offer higher spectral responsivity and lower detector capacitance. Voxtel's BSI APDs are supplied on flip-chip ceramic submounts, ready for wire bonding. The submount increases footprint and height, but also reduces parasitic capacitance between the BSI APD's submount bond pads relative to the bond pads situated directly on an FSI APD. Also, all of Voxtel's fiber-coupled assemblies are designed for use with our BSI APDs.
