Pulsed Laser Diodes & Arrays

At Excelitas, we provide optimized photonic technologies designed to provide enhanced capabilities for superior-performance and high-volume applications. These include our pulsed laser diodes and arrays which we design, manufacture, and further develop in world-class facilities located across-the-globe: Montreal, Canada; Wiesbaden, Germany; Singapore; Manila, Philippines; and Batam, Indonesia. 

We manufacture pulsed laser diodes in a variety of single and multi-channel arrays with central wavelengths at 905 nm and 1550 nm. They are offered in a variety of packages ranging from high-volume SMD to hermetically sealed metal-can TO packages.  Our pulsed laser diode and array lineup is just one of the various photonic detection solutions we develop for different applications. Here’s an overview of some of these products: 

• Avalanche Photodiodes (APDs): Our series of APDs offers high performance and low noise photon detection within a wide spectral range, such as 400 to 1100 nanometers (nm) of the C30902 of the “S” series. 

• PIN Photodiodes: Our series of PIN photodiodes are offered in both silicon and InGaAS materials. Our silicon PIN photodiodes come in a broad array of active areas, accommodating many applications. In addition, their PIN structure allows high quantum efficiency and fast response for photon detection in the 400 to 1100 nm. Our InGaAS PIN Detectors provide high quantum efficiency from 800 nm to 1700 nm. They feature low capacitance for extended bandwidth, high resistance for high sensitivity, high linearity, and uniformity within two percent across the detector active area. 

• Hybrid Optical APD Receivers: These solutions include a photodetector (PIN or APD) and a transimpedance amplifier in a hermetically sealed package. This module allows low noise pickup from the surrounding environment. It also reduces parasitic capacitances from interconnect, resulting in lower noise operation. 

• Low Light Level (L3D) Detectors & Modules: Our family of Single-Photon Counting Modules (SPCMs) are self-contained modules with a high range and sensitivity, detecting single photons of light over the 400 to 1100 nm wavelength range. Using a unique silicon avalanche photodiode (SLiK) with a circular active area, it reaches a peak photon detection efficiency of more than 65% at 650 nm over a 180 μm diameter.  

On top of the items above, we also provide application-specific components, photodiode arrays, blue enhanced silicon photodiode, fast response silicon photodiodes, industry standard silicon photodiodes, and infrared emitting diodes. 

Our Pulsed laser diodes are used in several demanding applications, including light detection and ranging (LiDAR), range finders, safety light curtains, adaptive cruise control, autonomous vehicles, and laser therapy. 

We observe industry standards and safety regulations in producing laser arrays with superior reliability. Manufacturing is done in our state-of-the-art ISO:9001-certified facility. Our team ensures all procedures comply with quality management and environmental requirements to deliver the best solutions to original equipment manufacturer (OEM) customers and their end-users. 

Absolutely. We develop our SMD laser array and diode chips so that they can be driven together or individually addressed, giving maximum flexibility to OEMs developing next-generation LiDAR systems. You are welcome to inquire about our approach to customization that allows for even greater levels of integration and reducing your time to market.
