A Lens Designer’s View Of Metaoptics: Aberration Theory For Flat Optics


By Dr. John R. Rogers and Dr. Yijin Ding. This paper covers a discussion of the Abbe Sine Condition and its implication for Flat Optics, including the effects of stop shift and substrate curvature. Following that, we apply Sweatt’s high index model of diffractive effects to develop a third-order aberration theory for diffractive, meta-, and hybrid optical systems, including the pos... » read more

Research Bits: August 19


Co-packaged optics Researchers from the Massachusetts Institute of Technology (MIT) and Bridgewater State University developed a new way to co-package photonic and electronic chips that uses existing automated pick-and-place assembly equipment in traditional fabs along with a less-expensive passive alignment process. “We’ve developed a packaging design [for integrating photonics with el... » read more

Research Bits: Jan. 28


Optical memory unit Researchers from Nokia Bell Labs developed a new type of optical memory called a programmable photonic latch that enables temporary data storage in optical processing systems. It is modeled after a set-reset latch. The integrated programmable photonic latch is based on optical universal logic gates using silicon photonic micro-ring modulators and can be implemented in co... » read more

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.

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
