Technical content for photonics and precision components
I write documentation and build tools for component makers, typically with 20 to 400 employees.
Semiconductor and EUV lithography
EUV scanners print chips with 13.5 nm light. Most materials absorb it, so the optics are multilayer mirrors in vacuum, and spectral purity filters keep the source’s deep-UV and infrared light off the mask and wafer.
I design EUV filters and Mo/Si multilayer mirrors and model them with CXRO data. I also design DUV coatings for 193 nm and 248 nm, and write the datasheets and application notes for all of them.
Photonics and optics
The sample projects cover photonics components, including TEC controllers and optical filters.
Filters and coatings
Angle-shift and blocking calculators, selection guides, and datasheets that state their test conditions.
Precision, molded and IR optics
Tolerance and material guides, datasheet refreshes, 3D models and outline drawings.
Polarization optics
Application notes on extinction ratio and angle of incidence, and selection guides.
Laser modules, drivers and TEC controllers
Thermal and drive calculators, application notes on wavelength stability, datasheets.
Fiber components
Loss-budget calculators, and connector and component selection guides.
Electro-optic and acousto-optic devices
Application notes on drive and bandwidth, and simple configurators.
Photonic integrated circuits
Design-in notes, coupling and packaging guides, and product pages.
Spectroscopy, imaging and metrology instruments
The optics and the system: resolution and throughput notes, and configuration guides.
Laser and broadband light sources
Selection guides, spectral and power calculators, and launch content.
Optomechanics and motion
Mount and stage selection guides, stability notes, and 3D models and drawings.
Precision components beyond photonics
I also write documentation and build selection tools for these component categories.
Test and measurement
Source-measure units, data-acquisition modules, probes and fixtures:
datasheets with conditions, selection guides, uncertainty calculators.
Scientific instruments
Cryostats, vacuum components, sample stages and spectrometer optics:
method notes and selection guides.
Motion and robotics
Stages, actuators, piezo positioners, grippers and controllers:
error-budget and settling-time calculators, integration notes, 3D models.
Industrial automation
Controllers, I/O, drives, pneumatics, connectors and enclosures:
product-page and datasheet refreshes, configurators.
Electronic components
Passives, magnetics, connectors, power modules, RF and microwave parts, thermal management, crystals and oscillators:
datasheet refreshes, parametric selection tools, derating calculators, KiCad symbols and footprints.
Based in California, working worldwide
I’m based in Ventura County, California, and work with companies across the US, Canada, the UK, Europe and beyond, remotely. Contact me to arrange a call. Every project uses public-release information only, and at kickoff I ask how your products are classified.
