Lab Equipment List

Tue, 10 Dec 2019 21:11:52 +0000

Here’s a partial list of EOI’s lab equipment. The list is heavily weighted towards electronic stuff, but we also have a very complete set of high precision optical and optomechanical parts: mounts, translation and rotation stages, lenses, prisms, polarization optics, gratings, filters, modulators, detectors, lasers, and fibres, for a start. This lets us try out new ideas quickly and build test setups to verify them.

If you’re also a fan of classical equipment, you can download manuals at Keysight (formerly Agilent, formerly HP) and Tektronix, liberatedmanuals.com, BAMA, Kurt’s Manuals, ElektroTanya.com, and K04BB. KE5FX’s GPIB Tools are pretty serviceable and also free. (NB: Keysight for some reason doesn’t allow deep links to their support pages—you have to go through the main page and select “support”.)

Lab Tour

Come on into the EOI lab and we’ll show you around!

We'll start with my office door and pan around to the right.

Since I do a lot of stuff on B-size vellum, the antique drafting table is appropriate. The print is Botticelli's Madonna del Libro.

Here I'm in the middle of going over the schematics for an ultrastable cavity-locked laser (Allen variance < 1E-10 @ 100,000 seconds)

Building Electro-Optical Systems: Making it all Work

Mon, 01 Jan 0001 00:00:00 +0000

This book is an attempt to provide a systematic and accessible presentation of the practical lore of electro-optical instrument design and construction: in other words, it’s the book I needed as a graduate student, but couldn’t find.

It’s intended in the first instance for use by oppressed graduate students in physics and electrical engineering, who have to get their apparatus working long enough to take some data before they can graduate. When they do, they’ll find that real-world design work has much the same harassed and overextended flavor, so in the second instance, it’s intended as a self-teaching guide and professional reference for working electro-optical designers.

Consulting

Consulting Services

I got started in consulting during my 20 years as a Research Staff Member at IBM T. J. Watson Research Center. I began in the Manufacturing Research department, building special instruments for unique manufacturing problems for which commercial solutions did not exist, such as scanned-probe and solid-immersion microscopy, and in-chamber particle detection. I also did a fair amount of firefighting, retrofitting semiconductor lithography equipment for new capabilities, and helping fix problems that were causing immediate revenue loss in manufacturing. Later I developed new classes of computer input device, advanced scanning technology, and a new class of photonic detector and switch for optical interconnection, based on metal-insulator-metal tunnel junctions.

Expert Witness Work

Mon, 01 Jan 0001 00:00:00 +0000

With more than 30 years’ experience designing electronic, optical, and mixed-technology systems, and 43 US patents issued or pending, I have amassed a lot of expertise in a number of fields, including optics, optoelectronics, electro-optics, photonics (especially silicon photonics), analog electronics, optomechanics, optical and atomic force microscopy, semiconductor processing, signal processing, simulation, electromagnetics, due diligence, and the drafting and technical interpretation of patents.

Expert witness work is one natural application, and I’ve been testifying expert in 35 matters to date, including inter partes reviews and cases in district court and before the International Trade Commission. I’m expert in optics, photonics, microscopy, and analog electronics, as well as some areas of semiconductor processing, metrology, and testing. I’ve also written about 150,000 lines of C++ code, mostly for electromagnetic simulation, instrument control, and embedded applications, so I do a lot of reverse engineering and source code review as well.

Patents

Mon, 01 Jan 0001 00:00:00 +0000

Here’s a list of links to PDFs of the patents on this site. A few of these cases were also filed overseas. We’ve also recently filed a provisional application on the thermal Faraday shield.

I also do a fair amount of expert witness work in patent and trade secret cases. I’m always interested in new work, so send me an email and let’s talk about your application.

Recent Work

Mon, 01 Jan 0001 00:00:00 +0000

EOI works with customers of all sizes, from garage startups and university research groups to the largest companies in the electronics, defense, biomedical, and semiconductor equipment industries. We do research, technology selection, product design, IP licensing, and expert witness work in both patent and trade secret cases. We’re always ready to help with debugging and firefighting as well—we learned some of this stuff the hard way too.

One problem that comes up again and again in doing measurements is that we need the apparatus to be quieter than the thing we’re measuring, ideally by at least a factor of two. Besides quiet, it should be wideband, have an accurately known gain that’s flat with frequency, have a clean step response, and generally do its job while keeping itself out of the way. There’s a wealth of detail in our app note AN-1 on photoreceiver testing.
