Did you hear about the new Ansys Speos Live Preview Virtual Lighting Controller?? Continue your result experience journey with Live Preview thanks to the new capabilities accessible from its intuitive user interface. Live Preview offers the possibility to individually control light sources as a post processing of the result, with Virtual Lighting Controller. Sources can be tuned individually or by group at once, entering numerical values or using the slider. Light levels are instantaneously updated, without restarting the GPU simulation. Lighting configurations can be created and used during simulation. Those configurations are also kept when exporting the result as a xmp file. Combined with interactive update, users can considerably reduce the number of simulations to launch and rely more on immediate memory in their design process. Join our webinar on September 12 to learn more about Ansys Speos Live Preview updates and explore all the latest features in the 2024 R2 Release of Ansys Zemax OpticStudio, Ansys Lumerical, and Ansys Speos.

Did you know that you can simulate lasers with external passive microring resonator circuits and narrow (sub-MHz) linewidths using Lumerical and include advanced physics effects such as mode hopping? The evolution of lasers is moving towards lasers with widely tunable frequency range and narrow linewidths. This could be achieved by coupling the optical gain medium to external low loss passive optical resonator circuits with larger resonator lengths and frequency selectivity. Using microring resonators in the passive circuit offers advantages such as simpler fabrication compared to alternatives like Bragg gratings, longer optical paths due to multiple round trips in the microring, and efficient frequency tunability. The frequency tunability of microrings enables widely tunable lasers, while the longer effective resonator length enables narrow linewidths. Leveraging our advanced Travelling Wave Laser Model (TWLM) in INTERCONNECT, we created a new application gallery example demonstrating accurate simulation of these types of lasers and effects. And thanks to our recent Optical Frequency Noise Spectrum Analyzer (OFNSA) model in INTERCONNECT, it is also possible to measure extremely narrow linewidths in a computationally efficient way.

Tech Tip Tuesdays with Ansys Optics: Parking Assistance Camera Integration Park assist cameras are critical for enhancing vehicle safety, aiding drivers with precise parking maneuvers by providing clear visibility and a comprehensive field of view. Evaluating camera performance across various vehicle conditions is essential to ensure these systems function reliably. In this article, we present a straightforward workflow for integrating park assist cameras, allowing us to proactively address potential issues and refine the specifications of both the optics and the sensor. We use Ansys Zemax OpticStudio to design and export the optical system, then leverage Ansys Speos to position the camera and ensure it meets parking regulation standards such as FMVSS 111. Finally, we’ll generate the final sensor image using the Speos Sensor System Exporter. Here are the steps: Step 1: Lens system design export with Ansys Zemax OpticStudio Transfer a Reduced Order Model from Ansys Zemax OpticStudio to Ansys Speos. Step 2: Lens system integration with Ansys Speos Assess the camera performance on the vehicle. Step 3: Sensor image generation using Speos Sensor System Exporter Generate a camera image or movie file from a simulation result.

Ansys Optics Fundamental Fridays - Silicon Photonics Silicon photonics (#SiPh) is a platform for constructing photonic integrated circuits (PIC) for optical communication, high-speed data transfer, and photonic sensing devices. The semiconductor substrate material is a silicon-on-insulator (SOI) wafer. Standard #semiconductor manufacturing processes are used to create components on a #photonic layer from silicon (Si), which is transparent to infrared light. Silicon dioxide (SiO2) or air is placed around the silicon to create a high refractive index difference, causing the light traveling in the components to travel through the circuit with very little loss. On-chip photonic integrated circuits are very compact, use less power, and operate at higher speeds (over 100 Gb/s) than traditional photonics devices, transferring information faster and more efficiently than electrical circuits. Advantages of Silicon Photonics Using light to carry information has significant advantages over electrons, radio waves, or microwaves. Light's higher frequency and its multiple modalities (frequency, amplitude, phase, etc.) allow for transmitting more information with low power consumption. These advantages are multiplied when the photonic devices are built into the same chip as the electronics needed for their operation, enabling the use of low-cost mass-production manufacturing processes. Because the technology combines optical components with the electrical circuits on the same chip, optoelectronic devices can be packaged into a smaller form factor than separate optical and electrical solutions. Because light travels through the waveguides with very little loss and because of their microscopic size, silicon photonic devices consume less energy than electrical or stand-alone optical devices. However, the most significant advantage of silicon photonics is its use of existing #CMOS manufacturing systems. Semiconductor manufacturers worldwide create more than one trillion chips of various kinds a year. Companies leverage the tools used to design, manufacture, package, and test semiconductor hardware for silicon photonics technology. Many semiconductor foundries are establishing standards for photonic integration designs, enabling faster, less expensive, and more robust new product development. Applications The most common use is in high-speed data transfer over fiber optics. Companies are focusing on improving the capabilities of optical transceiver chips to make them available for a wider range of applications. Some emerging applications that are leveraging SiPh technology for photonic components include: ▪️ Photonic sensors ▪️ #Lidar ▪️ Quantum computing and networking Read the full article to learn more: https://ansys.me/3AsOk3Q #SiliconPhotonics #QuantumComputing
