Did you know that the first digital gradient search optimization algorithm for the alignment of optical fibers and photonic devices was invented by our photonics expert Scott Jordan back in 1987? Since those early days, alignment solutions have evolved tremendously to enable the massive scale-up in the manufacturing and testing of novel photonics devices which are at the heart of quantum computing, virtual reality, LIDAR (light detection and ranging), and more.

Alignment has been the very bottleneck for productivity in #siliconphotonics and photonic integrated circuits (PIC). With the FMPA (Fast Multichannel Photonics Alignment) algorithm developed by Scott Jordan and implemented in the unique motion and positioning solutions from PI (Physik Instrumente) Group, alignment ist reduced to a matter of a fraction of a second. It even works with Arrays (!) which makes the whole thing absolutely unique! Still in doubt? Just ask your local PI representative for a demo.

Single photon InGaAs photodetector With the rapid development of LiDAR, the light detection technology and ranging technology used for automatic vehicle tracking imaging technology also have higher requirements, the sensitivity and time resolution of the detector used in the traditional low light detection technology can not meet the actual needs. Single photon is the smallest energy unit of light, and the detector with the ability of single photon detection is the final tool of low light detection. Compared with InGaAs APD photodetector, single-photon detectors based on InGaAs APD photodetector have higher response speed, sensitivity and efficiency. Therefore, a series of researches on IN-GAAS APD photodetector single photon detectors have been carried out at home and abroad. Researchers from the University of Milan in Italy first developed a two-dimensional model to simulate the transient behavior of a single photon avalanche photodetector in 1997, and gave numerical simulation results of the transient characteristics of a single photon avalanche photodetector. Then in 2006, the researchers used MOCVD to prepare a planar geometric InGaAs APD photodetector single photon detector, which increased the single-photon detection efficiency to 10% by reducing the reflective layer and enhancing the electric field at the heterogeneous interface. In 2014, by further improving the zinc diffusion conditions and optimizing the vertical structure, the single-photon detector has a higher detection efficiency, up to 30%, and achieves a timing jitter of about 87 ps. In 2016, SANZARO M et al. integrated the InGaAs APD photodetector single-photon detector with a monolithic integrated resistor, designed a compact single-photon counting module based on the detector, and proposed a hybrid quench method that significantly reduced avalanche charge, thereby reducing post-pulse and optical crosstalk, and reducing timing jitter to 70 ps. At the same time, other research groups have also carried out research on InGaAs APD photodetector single photon detector. #Optical #photonics #semiconductor #Optics #opticalcenter #SiliconPhotonics #photodetectors #optomechanics #laser Read more: https://lnkd.in/emjZdKau

How Photons Help Us See—and How We’re Taking Them Further Every second, tiny packets of energy called photons are on a mission to light up our world. Here’s how their journey unfolds: A photon begins at its source—whether that’s the 🌞 sun, a 💡 light bulb, or even your 📱 smartphone screen. It races outward at the speed of light (that’s 300,000 kilometers per second!). Along the way, it reflects, refracts, or scatters, navigating surfaces, water droplets, and dust particles. When a photon finally reaches your eye, the real magic happens. It’s absorbed by retinal cells, setting off a chain reaction that converts light into signals for your brain to decode. The result? The vivid images, colors, and scenes that shape how we see the world🌍. At Scantinel Photonics, we’re giving photons a new mission: helping machines see. Using 🚘 FMCW LiDAR, we harness photons to build precise 3D maps, enabling systems to perceive their surroundings with exceptional accuracy. It’s a continuation of their journey—one that’s redefining how technology understands and interacts with the world. #Photonics #FMCWLiDAR #AutonomousTechnology #Innovation #Scantinel

🔬 𝗦𝗶𝗺𝘂𝗹𝗮𝘁𝗶𝗼𝗻 𝗼𝗳 𝘁𝗵𝗲 𝗪𝗲𝗲𝗸 🔬 📡 Silicon photonics for LiDAR is an exciting area of technology that leverages the advantages of silicon-based optical components to enhance the performance and efficiency of LiDAR systems. It is a crucial technology shaping the development of next-generation self-driving cars. Significant research in this area has focused on long waveguide grating antennas (WGAs). These antennas are crafted by introducing periodic perturbations in an integrated waveguide. They have emerged as a favored option for achieving expansive apertures because they can extend lengthwise to several millimeters. This week, we highlight an example of WGA modeling. Using a dual-layer design, a unidirectional emission pattern is achieved via destructive interference of the downward emission and constructive interference of the upward emission. The far-field emission pattern can be obtained with a low computational cost by modeling only a small area around the antenna and performing near-field to far-field projection.
