Excelitas Expands InGaAs Based APD Family

New product innovations in Avalanche Photodiodes offer an enhanced optical damage threshold and increased reliability
Excelitas Technologies has introduced two new products to its line of high-speed, low-light analogue APD LLAM receiver modules, the LLAM-1550E-R2AH and the LLAM-1550E-R08BH.

The modules feature enhanced optical damage thresholds and an increased 1550nm peak response.   

Excelitas says the LLAM-1550E modules offer greater resilience when exposed to higher optical power densities and increased reliability for a broad range of mission-critical applications.

The LLAM-1550E modules were developed specifically for situations requiring a wide dynamic operating range, high frequency response, extremely low-light detection scenarios such as laser imaging detection, combat, range finding and free-space communication.

The hermetically sealed components within a TO housing, are capable of detecting extremely low-light signals with a bandwidth up to 200MHz and have an excellent spectral response between 900 - 1700nm.

Excelitas’ LLAM series is offered as a standard, RoHS-compliant, commercial off-the-shelf product. It can also be customised for bandwidth and gain optimisation, with the use of different APDs and packages.

“We are proud of our legacy in providing mission-critical solutions to our defence and aerospace industries," says Michael Ersoni, senior vice president and general manager, Excelitas Technologies’ global detection business.

“By extending our line of APD offerings with the new LLAM-1550E modules, we continue to deliver innovative, customisable products that meet the specific needs of our customers," he continues.

Excelitas will be displaying the LLAM-1550E modules at the 2013 SPIE Defence, Security, and Sensing show (Booth #1842) from April 30th to May 2nd, 2013, in Baltimore, Maryland.

AngelTech Live III: Join us on 12 April 2021!

AngelTech Live III will be broadcast on 12 April 2021, 10am BST, rebroadcast on 14 April (10am CTT) and 16 April (10am PST) and will feature online versions of the market-leading physical events: CS International and PIC International PLUS a brand new Silicon Semiconductor International Track!

Thanks to the great diversity of the semiconductor industry, we are always chasing new markets and developing a range of exciting technologies.

2021 is no different. Over the last few months interest in deep-UV LEDs has rocketed, due to its capability to disinfect and sanitise areas and combat Covid-19. We shall consider a roadmap for this device, along with technologies for boosting its output.

We shall also look at microLEDs, a display with many wonderful attributes, identifying processes for handling the mass transfer of tiny emitters that hold the key to commercialisation of this technology.

We shall also discuss electrification of transportation, underpinned by wide bandgap power electronics and supported by blue lasers that are ideal for processing copper.

Additional areas we will cover include the development of GaN ICs, to improve the reach of power electronics; the great strides that have been made with gallium oxide; and a look at new materials, such as cubic GaN and AlScN.

Having attracted 1500 delegates over the last 2 online summits, the 3rd event promises to be even bigger and better – with 3 interactive sessions over 1 day and will once again prove to be a key event across the semiconductor and photonic integrated circuits calendar.

So make sure you sign up today and discover the latest cutting edge developments across the compound semiconductor and integrated photonics value chain.
