Tech Tip Tuesdays with Ansys Optics: Physical Optics Propagation (POP) Support for Black Boxes With the 2024 R2 release of Ansys Zemax OpticStudio, users can now run the POP algorithm for diffraction calculations at each surface even through the Black Box surface, which was previously not permitted. Users who want to share the capability of an optical element without sharing the exact optical prescription have long made use of the Black Box to map input rays to output rays while hiding the inner workings of the included surfaces. Since POP uses a field model of a wavefront rather than a ray-based model, the Black Box was incompatible with it. Now, POP has been upgraded to handle the field calculations even with a Black Box surface. No new settings need to be made for either tool. Users who examine the Properties of the Black Box and click on the Physical Optics tab will see the options removed entirely – the software handles everything, which no opportunity to use the wrong settings. The surface properties in the Physical Optics tab will be maintained during the Black Box export, so common options like resampling the beam or using rays to propagate to the next surface will be retained for the Black Box surface and cannot be changed. Diffractive effects within the Black Box will be preserved. Experience the power of Ansys Zemax OpticStudio optics design software.

Ansys Lumerical SPARK! Let’s explore fiber to photonic chip coupling with a microlens and edge coupler. In photonics, coupling your signal onto and off the chip presents a unique challenge that requires precise alignment and complex packaging. Given that coupling performance is critical to the chip’s functionality, it may not be surprising that this design problem represents a significant portion of the technology cost through lost yield, overengineering and additional processing/packaging expenses. With industry trends pushing towards co-packaged optics within 3D integrated circuits, it becomes imperative to develop workflows to accurately model reliability and make economically viable design decisions. While industry standards do not yet exist, coupling is achieved through standard devices like a grating coupler, evanescent coupler or edge coupler. Edge couplers are fabricated at the edge of the chip with an optical fiber brought into proximity and a large footprint spot size converter (SSC) to adiabatically transform the larger fiber modes into the modes of the photonic waveguides. Although there are limitations on the placement, and the size is prohibitive, these devices can offer broadband capabilities, polarization insensitivity and low insertion loss (IL). Eigenmode expansion (EME) is an efficient and accurate method to analyze guided mode optics along a consistent propagation axis and is perfectly suited for efficiently simulating SSC devices, which are often too large for FDTD. Our previous edge coupler example assumed perfect contact and alignment between the fiber and SSC, which is reasonable when looking at nominal IL; however, this doesn’t help understand the tolerance to misalignment or help design systems that are robust under manufacturing/packaging variations. For this reason, we have generalized the approach incorporating Ansys Zemax OpticStudio's physical optics propagation (POP) tool to reliably model misalignment and analyze more complex optical systems. Here are the steps: Step 1: Fiber Optical Analysis in Lumerical MODE (Optional) Step 2: Microlens Alignment in Zemax OpticStudio Step 3: Free Space to Guided Modes in Lumerical FDTD Step 4: Spot Size Converter in Lumerical MODE Read the full article here to learn more: Fiber to Photonic Chip coupling with a microlens and edge coupler – Ansys Optics https://ansys.me/481Azpo And join our webinar on October 17th! https://ansys.me/4h2gROn #Photonics #PhotonicChip #PhysicalOpticsPropagation #EdgeCoupler #Microlens

Tech Tip Tuesdays with Ansys Optics: Multisection DFB laser with partially corrugated gratings with Ansys Lumerical INTERCONNECT We have a new application example that simulates a distributed feedback (DFB) laser with a passive feedback section and a partially corrugated grating using Ansys Lumerical INTERCONNECT. This example showcases our newly released multisection feature for the traveling wave laser model (TWLM), introduced in the version 2024R2. DFB lasers with passive feedback sections are important for high-speed operation, cleavage yield sensitivity, and single-mode stability. DFB lasers with partially corrugated gratings and passive feedback (PCG-PFL) are designed to address these issues. The PCG structure enables DFB lasers to maintain a high single-mode yield (SMY), even with a high-reflection coating on the rear facet and strong reflection from the integrated passive section. In this example, the side-mode suppression ratio (SMSR) is calculated and plotted as a function of the facet phase of the DFB laser with a partially corrugated grating and compared to that of a DFB laser with a uniform grating. The results shows that SMSR is lower for the uniform grating DFB compared to the partially corrugated one across most facet phase changes. In addition, the SMY is calculated for #SMSR higher than 35 dB and it is 84% for the partially corrugated and 50% for the uniform grating. This is consistent with the existing literature.

Join us on October 10, 2024, to learn about a new workflow integrated into Ansys Zemax OpticStudio that simplifies obtaining the Mueller matrix—a powerful tool for understanding and managing polarization effects in optical systems. 📅 Date: October 10, 2024 🕘 Session 1: 9am EDT 🕒 Session 2: 2pm EDT What is the Mueller Matrix? The Mueller matrix is a key tool in polarization optics that describes how the polarization state of light changes when it interacts with an optical system. In simpler terms, it helps optical designers understand how their systems alter light's polarization, which is crucial for optimizing image clarity, reducing glare, and improving overall performance. For instance, in applications like microscopy, displays, and remote sensing, controlling polarization can be the difference between achieving high-quality imaging and dealing with unwanted reflections and contrast issues. By using a Mueller matrix, designers can model how light’s polarization will behave after interacting with their optical components, allowing them to fine-tune performance. The Mueller matrix transforms the Stokes parameters, which describe the light’s polarization state, helping you assess its behavior in your system. Each element in this 4x4 matrix defines how different properties of light—such as its intensity or polarization type—are affected by the system. In this webinar, we will walk you through a new workflow integrated into Ansys Zemax OpticStudio that simplifies the creation of Mueller matrix maps, enabling rapid analysis across the optical field of view. This innovative solution helps designers quickly evaluate polarization effects, allowing them to: ◾ Control reflections and glare to improve image quality ◾ Enhance polarization control in optical systems ◾ Boost overall design efficiency by reducing the time spent on manual calculations What You’ll Learn: ◾ How to utilize the Mueller matrix to evaluate polarization transformations in your optical system ◾ How to create a Mueller matrix map to improve your system's polarization control ◾ Techniques for generating an average Mueller matrix map for rapid polarization analysis This is an essential session for Optical Engineers, Photonic Engineers, and Engineering Managers who want to streamline their polarization analysis workflows and enhance system performance.
