Synopsys OptoCompile Ansys Lumerical is answer? (synopsys owns both) synopsys stock is very stale ytd, is there something of value here

codex and ffmpeg. simulation results are from comsol and lumerical fdtd

$SNSP 가 인수한 Lumerical/Ansys 는 Photonics의 standard sim tool로 없어서는 안될 시뮬레이터입니다. 제가 알기로 Ansys 인수 하고 부정적 여론이 많았다고 하는데, (높은 비용) 전 요즘 포토닉스 시장을 보면, 성공적 베팅이 아니었나 싶습니다. 이를 통해 소자 디자인, 회로 시뮬, 칩 설계까지 EPIC를 아우르는 시장을 갖게 된 것 같습니다. (내 주식은 마이너스지만 ㅠ) 파파존스님께서 공유해주신 SNUG 글 재밌게 잘 봤습니다 😃

I’ll try to learn the basics of Lumerical—it’s used for optics simulations. I think it will be much more helpful for my project than PyMeep FDTD and could have a greater impact. I have about two weeks left, and the project will be wrapping up soon.

Lightmatter의 행보가 정말 매섭습니다. 광컴퓨팅과 광연결 시대가 우리 생각보다 훨씬 빠르게 다가오고 있음을 매일 실감하게 됩니다. 특히 우리가 주목해야 할 지점은 $SNPS 의 전략적 움직임입니다. 이들은 단순히 다양한 파운드리의 PDK를 지원하는 보조적인 역할을 넘어, 광학 시뮬레이션의 표준으로 통하는 Ansys/Lumerical 인수를 통해 독보적인 위치를 점하고 있습니다. 현재 $SNPS 의 주가 차트 자체는 별로지만 (손실중이긴합니다.) 다소 무겁게 느껴질 수 있지만, 회사 내부의 기술적 해자를 들여다보면 이야기가 달라집니다. 이들은 실리콘 포토닉스 설계에서 가장 핵심적인 시뮬레이션 툴을 제공하며 설계부터 물리적 검증까지의 워크플로우를 하나로 통합하고 있습니다.

I need you to upload all your COMSOL, ANSYS, Abaqus, Siemens STAR-CCM , OpenFOAM, CST Studio, Lumerical, Synopsys TCAD, MATLAB/Simulink, and VASP simulation result gif/mp4 to youtube so Genie-999 can run full-stack multiphysics simulations in 8K realtime at 30 FPS with 1e-6 residual error.

Actually I'm surprised they get so much directionality from incoherent emitters. Can local coupling between neighbours result in coherent behaviour over a wide area ? I'm not sure I understand what they do with Lumerical.

i'm more familiar with the on-chip stuff, where the sim tools are FDTD and FEM (lumerical, comsol, synopsis beamprop, flexcompute tidy3d etc), and you could build your own circuit level sims using pytorch, or use [sax](flaport.github.io/sax/). there are many people here who are experts in free space optics stuff, @apraxophobia does noblinear optics for fs lasers, and @BobNiffenegger 's lab developed a [code to CAD optical layout tool](websites.umass.edu/rniffeneg…)

i'd like to think that flexcompute forced them to put lumerical FDTD onto EC2. would they support GPUs if we trash talk them more?

实验室主机第一次爆显存竟然是不是因为神经网络而是 lumerical😇 真的太穷了，当时只能买 3060 12G，现在要跑路了也懒得更新了

Love and hate relationships with comsol. Way less beginner Friendly than lumerical fdtd for optics. Troubleshooting in comsol = pain. Meep was my first fdtd, but then switch to lumerical because of gui. Been wanting to try felxcompute for metasurface and waveguide

【#Ansys 2025 R1リリース情報⑤】 2025年3月に最新バージョン登場！ ✨光学製品の機能強化✨ ✅Lumerical FDTDに新GUI導入 ✅Speosに材料情報としてAxFファイルがインポート可能に ✅OpticStudioで、レンズ設計から製造フェーズへの移行の再現性向上 詳細やその他のアップデート情報はこちら👇

You are using Synopsys OptSim/Ansys Lumerical INTERCONNECT/Luceda IPKISS/GDSFactory for your photonics circuit simulation, I'm using pytorch, we are not the same. (this is probably a dumb idea but hey it got built-in tolerance analysis called backpropagation, and many benchmarking, visualization stuff) (Will make the coupler modeling more accurate & add more components etc)

轉傳 🔴6227茂綸 : 資安、機器人、CPO、輝達概念 🔘資安概念 茂綸去年底宣布收購數位資安系統股份有限公司 ，數位資安主要業務為資料外洩防護(DLP)解決方案Fortra、應鏈資安風險管控平台Panorays、工控資安專家Waterfall等，為因應生成式AI帶來的資安風險數位資安更率先代理Lasso，協助企業加強AI數據安全，成為企業Gen AI應用的最後防線，因此6227茂綸屬於市場較鮮為人知的資安概念股 🔘機器人 瑕疵檢測是製造業不可或缺的關鍵環節。傳統的自動光學檢測（AOI）系統難以達到95%以上的檢出率，且需耗費大量時間成本來蒐集樣本進行訓練，茂綸整合生成式AI與數位孿生技術，將可有效克服上述問題，加速AI瑕疵檢測的導入過程 在去年展覽中，茂綸攜手MetAI，展出先進瑕疵生成。該方案整合了Epson機器手臂的多元靈活性與強大運算能力，並利用MetAI的MetSynthesizer演算法。使用者只需輸入圖檔資料，即可在虛擬平台上實現數位孿生環境，模擬AOI設備的光源條件，生成擬真的3D場景。這使得系統能夠產生黃金樣本、零件缺失、零件偏移等多樣化的資訊 🔘輝達(NVIDIA)合作關係 茂倫與全球加速運算領域先驅NVIDIA合作，成為NVIDIA在台灣地區的代理商夥伴。除原代理的NVIDIA Networking產品外，茂綸更擴大代理NVIDIA的軟硬體，包含人工智慧系統DGX，端對端雲端原生人工智慧軟體套件AI Enterprise，高效能運算程式框架(High Performance Computing)，致力於以更完整的解決方案增強NVIDIA產品在台灣地區的銷售與技術服務。茂綸為全台唯一同時代理NVIDIA GPU以及NVIDIA 網路相關產品的代理商 🔘矽光子(CPO) Ansys過去與台積電(2330)共同透過微軟Azure NC A100v4系列虛擬機器，在 Azure AI基礎架構上執行的NVIDIA加速運算，將Ansys Lumerical FDTD光子模擬速度提升超過10倍。積體光路是跨產業應用不可或缺的一部分，包括資料通訊、生物醫學工具、汽車光學雷達系統、人工智慧等。Ansys在台灣的代理合作夥伴就是茂綸，因此茂綸等同於跟著Ansys搭上矽光子商機 #小作文零級分
