Reduce Augmented Reality Device Time-to-Market by Bringing Manufacturing Impact to Optical Simulation


Disruptive AR systems will push the limits of optics: limits in design, limits in manufacturing, and limits in overall system integration. The trend of optical components being integrated into more complex miniaturized systems is impacting optical software. Optical design software has been around for decades to design, simulate, and analyze any optical component from lenses and mirrors to light... » read more

PCIe Over Optical: Transforming High-Speed Data Transmission


With the rise in AI requiring new computing models and enhanced data transmission methods to cope, the necessity for innovative, high-performance, and low-latency connectivity solutions has never been more apparent. PCIe over Optical is set to play a key role in enabling the growth of AI, and here we examine some of the intricacies of PCIe over Optical to explore its implementation, challenges,... » read more

Next-Gen High-Speed Communication In Data Centers


Data centers are being flooded with data. While more of it needs to be processed locally, much of it also needs to be moved around within a system and between systems. This has put a spotlight on a variety of new optical technologies and methodologies. Yang Zhang, senior product marketing manager at Cadence, talks about the rapid increase in different types of optics and optical scenarios being... » read more

The Race To Zero Defects In Auto ICs


Assembly houses are fine-tuning their methodologies and processes for automotive ICs, optimizing everything from inspection and metrology to data management in order to prevent escapes and reduce the number of costly returns. Today, assembly defects account for between 12% and 15% of semiconductor customer returns in the automotive chip market. As component counts in vehicles climb from the ... » read more

Stress tensor mesostructures for deterministic figuring of thin substrates


New research paper from MIT and University of Arizona, funded by NASA. Abstract "Accessing the immense value of freeform surfaces for mass-sensitive applications such as space optics or metaform optical components requires fabrication processes that are suited to figuring thin substrates. We present stress tensor mesostructures for precisely correcting figure errors, even after microstruc... » read more

Graphene oxide 2D films integrated with nanowires and ring resonators for enhanced nonlinear optics


New research paper from Optical Sciences Centre, Swinburne University of Technology. Abstract "We report enhanced nonlinear optics in nanowires, waveguides, and ring resonators by introducing layered two-dimensional (2D) graphene oxide (GO) films through experimental demonstration. The GO films are integrated on silicon-on-insulator nanowires (SOI), high index doped silica glass, and sili... » read more

An achromatic X-ray lens


Abstract "Diffractive and refractive optical elements have become an integral part of most high-resolution X-ray microscopes. However, they suffer from inherent chromatic aberration. This has to date restricted their use to narrow-bandwidth radiation, essentially limiting such high-resolution X-ray microscopes to high-brightness synchrotron sources. Similar to visible light optics, one way t... » read more

Electro-optic spatial light modulator from an engineered organic layer


Abstract "Tailored nanostructures provide at-will control over the properties of light, with applications in imaging and spectroscopy. Active photonics can further open new avenues in remote monitoring, virtual or augmented reality and time-resolved sensing. Nanomaterials with χ(2) nonlinearities achieve highest switching speeds. Current demonstrations typically require a trade-off: they eith... » read more

Power/Performance Bits: Jan. 25


Nanoscale 3D optics Researchers at Rice University and University of Houston are using 3D printing to build nanostructures of silica for micro-scale electronic, mechanical, and photonic devices. “It’s very tough to make complicated, three-dimensional geometries with traditional photolithography techniques,” said Jun Lou, a professor of materials science and nanoengineering at Rice. �... » read more

The Role of InGaN Quantum Barriers in Improving the Performance of GaN-based Laser Diodes


Abstract: "In this work, different aspects which have influences on device performance of blue laser diodes (LDs) when using InGaN instead of GaN as quantum barrier (QB) layers are investigated theoretically and experimentally. In the modeling calculation, it is found that the threshold current of LDs with InGaN QB layers is reduced obviously, but the slope efficiency is not largely improved... » read more
