I’ll bet that you didn’t know that the original concept for what became the Apple Thunderbolt interface involved optical communication. Well, in this fascinating podcast with Dr. Mader, you will learn that intriguing backstory and much more.

Mader also provides a helpful introduction to silicon photonics technology and applications. Importantly, OpenLight’s business model is designed to allow them to become an Arm-like IP provider for silicon photonics. “We’re the first open siliconics platform that has the lasers and amplifiers integrated on the chip,” explains Mader.

With the OpenLight Process Design Kit (PDK), customers can integrate InP lasers and amplifiers directly into their silicon IC designs at Tower Semiconductor. While the silicon can be employed to guide, modulate, and detect light, you need the InP to amplify. OpenLight literally brings the silicon and the InP together with molecular bonding.

While silicon photonic is already making inroads in a number of important applications, Mader is “excited about the long tail of applications” enabled by OpenLight and their customers.

In addition, Mader recounts his rich technology background that includes developing a patent while interning at Apple, being involved in an early Amazon commercial product, directing engineering at a startup that was inquired by Intel, and his family connections to the legendary Fairchild Semiconductor and our podcast’s name inspiration, Gordon Moore.

So, listen in for other interesting tidbits from this discussion with Mader, including these technical insights:

-A clear description of a silicon photonics system -What makes a quality integrated laser? -How amplitude modulation (AM) and phase modulation (PM) are employed is laser systems

Ananth Avva is “a big believer that if you give human beings the right type of information and you contextualize it, they will make the right decision ultimately for the organization.” In his current role at Altium as the Senior Vice President and General Manager of Cloud Platform, he is leading efforts to improve and accelerate collaboration because “collaboration trumps everything else” as it drives speed to market, lower costs, and more efficient development. He has seen companies attempt to transition engineering teams to software-as-a-service (SaaS). In his experience, “that usually goes sideways pretty fast.” With Altium 365, Avva and his team are trying to seamlessly bring SaaS into engineering. Their goals are to enable what they call shifting left and shifting right. When shifting left, they aim to take decisions that were traditionally late in the product life cycle and move those requirements earlier in the design process. This can allow the procurement, operations, compliance, and manufacturing teams to provide vital context for better design decisions. Similarly, shifting right passes design information downstream more quickly to avoid costly delays or respins. If your organization is developing electronic products, you will benefit from this Moore’s Lobby podcast discussion hosted by Daniel Bogdanoff. Avva explains that companies consistently overestimate the cost of change and underestimate the benefits. They may also have the wrong “whys” behind why not to change. He goes on to explain that these can be “a bit of a phantom menace.” In his opinion, these are changes all companies will need to make to remain competitive in the market: Let's say you don't do it. The world is headed that way anyway, so what happens? Let's fast-forward five years, you're gonna have to do it.…

After beginning his career with Hewlett-Packard, David Su met a friend for lunch to learn about a new startup called Atheros. He was so excited by the vision to develop world-changing products that Su “went for lunch and never left.” At Atheros, Su had a “front-row seat” developing wireless WAN technology that transitioned from novelty to necessity while Atheros grew from a startup to a billion-dollar behemoth. That little startup was eventually acquired by another company you may have heard of: Qualcomm. And what led Su to get involved with another startup? Well, lunch, of course. Su and his friends recognized that they could use their design experience to help fix a problem that was partially of their own making: battery consumption for wireless RF products. This was the genesis of Atmosic. With his decades of design experience, Su admits that he stands on the shoulders of giants when creating new low-power products. The company has recently expanded its RF IC offerings from Bluetooth to Zigbee and Matter over Thread. When asked how an IC design team knows when they have become either too structured or too unstructured, Su thoughtfully answered that if you never create anything innovative or your chips don’t work, you have probably fallen into one of those two ditches. You will want to join our host, Daniel Bogdanoff, as he discusses CMOS RF, energy harvesting, and the importance of teams with Su. They touch on many other interesting topics including: -What he remembers most fondly from his days at Atheros. -A development failure for one technology that led to success for another. -The balance of circuits, system, and software design necessary to optimize product performance.…

While leading the system design of new head-word displays for fighter pilots, Tomide Adesanmi was most excited when he got a chance to innovate. However, like most electronics design engineers, he found that the majority of his time was spent searching distributor sites for components, drawing symbols, and working with spreadsheets. Engineers can also relate to the anxiety he felt, worrying that he might have made a silly mistake by missing a tiny detail on “page 243 of the datasheet” for a microcontroller. So, he quit his job to try to tackle the mundane problems of design using “good software, good algorithms, and electronics.” A few months later, Circuit Mind was founded. Adesanmi and the Circuit Mind team aim to allow designers to quickly optimize designs with variable weighting on size, power, cost, parts availability, and more.
