If you are interested in electronics, history, or simple amazing stories, you will enjoy this podcast interview with our Moore’s Lobby host, Daniel Bogdanoff. Mike Engelhardt has been developing simulation tools since 1975. He is best known for creating LTspice, which is believed to be the most widely distributed and used SPICE analog electronic circuit simulator in the world. Recently, he realized that he could take advantage of the massive improvements in both hardware and software to develop a radically improved circuit simulation engine; thus, QSPICE was born. Engelhardt explains how he...

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...

Thomas Keller is the Director of Platforms and Core Technology at u-blox. He learned early in his career that technology development does not always progress in a perfectly straight line. During his PhD studies, he worked on Orthogonal Frequency-Division Multiplexing (OFDM) as a candidate technology for 3G cellular network deployment. OFDM lost that initial tech battle to Code-Division Multiple Access (CDMA) but later returned in LTE cellular systems. In this fascinating conversation, Keller discusses the challenges facing the industry today as low-power, low-bandwidth, low-cost IoT devices...

If you enjoy hearing passionate people talk about jobs they love and technology that fascinates them, you are in for a treat. Noah Gedrimas grew up with a love of vehicles—cars, tractors, construction equipment, and snowmobiles. In college, he built a one-fifth-scale car and then programmed it to self-park, which led him to a “newfound respect for mechatronics” and its ability to support really complex maneuvers. In this interview, Gedrimas reflects with enthusiasm on his time at Continental Automotive, working on everything from autonomous valet parking to electric shuttles and...

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...

Steve Klinger, Vice President of Product, joins the Moore’s Lobby podcast to discuss how LightMatter is using silicon photonics to improve speed and reduce power consumption in AI data centers. With two previous $1B+ startups under his belt, Klinger knows a thing or two about identifying successful technology solutions to current industry challenges. While compute performance continues to grow rapidly, interconnect has not been able to keep pace. In this episode, Klinger explains how LightMatter’s flagship product, Passage, creates a programmable optical fabric for the efficient...

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...
info_outlineSteve Klinger, Vice President of Product, joins the Moore’s Lobby podcast to discuss how LightMatter is using silicon photonics to improve speed and reduce power consumption in AI data centers. With two previous $1B+ startups under his belt, Klinger knows a thing or two about identifying successful technology solutions to current industry challenges. While compute performance continues to grow rapidly, interconnect has not been able to keep pace. In this episode, Klinger explains how LightMatter’s flagship product, Passage, creates a programmable optical fabric for the efficient interconnect of chiplets and other silicon ICs.
Klinger explains that they are trying to solve the problem of efficiently accessing all of the bandwidth on one chip and sharing it with another chip. If they can improve the interconnect bandwidth density, it will allow performance scaling to continue increasing at the workload level. Klinger emphasizes, “There are data centers with hundreds of millions of dollars of GPUs sitting idle, waiting for the network topology or the interconnects to catch up.”
So, join our host, Daniel Bogdanoff, in this deep dive into silicon photonics with Klinger. In this discussion, they address many fascinating topics, including:
- What makes silicon photonics unique from traditional photonics?
- The common traits shared by Klinger’s previous $1B+ startups.
- The many job openings available at LightMatter.
