The IEEE Photonics Society / Standards Committee recently published a whitepaper on Fiber Attach. Transmission of light between or in and out of any photonic platform normally requires attachment to a fiber that is used as a flexible optical waveguide. An effective fiber attach involves many requirements and metrics that have so far involved decades of research. The presentation will cover the whitepaper in detail, some technical background, the path forward, and how to become involved.
Speaker: John S. Mazurowski of Penn State Applied Research Laboratory

Silicon Valley is commonly acknowledged as the tech capital of the world. How did Silicon Valley come into being, and what can we learn? The story goes back to local Hams trying to break RCA’s tube patents, Stanford “angel” investors, the sinking of the Titanic, WW II and radar, and the SF Bay Area infrastructure that developed – these factors pretty much determined that the semiconductor and IC industries would be located in the Santa Clara Valley, and that the Valley would remain the world’s innovation center as new technologies emerge, and be the model for innovation worldwide.
This talk will give an exciting and colorful history of development and innovation that began in Palo Alto in 1909. You’ll meet some of the colorful characters – Cyril Elwell, Lee De Forest, Bill Eitel, Charles Litton, Fred Terman, David Packard, Bill Hewlett, Bill Shockley and others – who came to define our worldwide electronics industries through their inventions and process development. You’ll understand some of the novel management approaches that have become the hallmarks of its tech startups. Many of these attributes can be found in other technology hubs; however, the SF Bay Area has five generations of experience, as well as a “critical mass” of talent, making it difficult for others to catch up. In this talk, the key attributes will be illustrated and analyzed, for consideration by other tech hubs, and for entrepreneurs interested in creating their own start-ups or understanding them.

Noise-Shaping (NS) SAR ADCs become popular recently thanks to their low-power and high-resolution features. This presentation first summarizes and benchmarks different discrete-time (DT) NS-SAR implementations in literature. An open-loop duty-cycled residue amplifier is selected as a power-efficient solution to realize high residue gain. Then, a digital-predicted mismatch error shaping technique is introduced to improve the DAC linearity. The proposed DT NS-SAR ADC achieves 80 dB SNDR, 98 dB SFDR in a 31.25 kHz bandwidth while consuming 7.3 μW. Next, the NS-SAR architecture is extended from DT operation to continuous-time (CT) operation. The ADC sampling switch is removed and the loop filter is duty cycled to realize the CT NS-SAR operation. Compared to DT designs, the CT NS-SAR ADC is easy to drive and has inherent anti-aliasing function. As a proof of concept, the proposed CT NS-SAR ADC achieves 77 dB SNDR, 86 dB SFDR a 62.5 kHz bandwidth with a power consumption of 13.5 μW.
