ThorLabs displays a keen understanding of graduate school - as of a few years ago, they’ve included snack boxes with many of their orders of optics components. The boxes include things like trail mix, granola bars, goldfish crackers, and fruit snacks - not, of course, that this influences any

Low-budget geeky grad school magnetic poetry: cut up the fridge magnet ads that they hand out at conferences and job fairs. If there’s any whitespace, go to work with a Sharpie. Thanks to some junk mail, I’ve got a pizza-themed set as well!

Light in a circular cavity makes a variety of standing wave patterns, some of which look like flowers, wagon wheels, or even tie-fighter spaceships. These images are from my simulations of the light in the cavities of nanolasers - each pattern is called a mode, and the smaller the laser,

The view inside one of our lab’s titanium sapphire infrared lasers - if you see a view like this, you’re doing something wrong. Specifically, you’re not wearing laser goggles around a 10W laser source (bad), and placing your eyeballs at beam height (very bad, yet done almost

The beachgoers flee as hulking monsters climb from the dark water… This is a scanning electron microscope image of some various-sized pillars that appeared on one of my samples during a plasma etching test. They’re made of semiconductor, and the bright plain beneath is silicon. Showing through the dark

Traffic looks like fireworks when viewed through diffraction glasses. You can pick up diffraction glasses for pretty cheap online - they’re popular as a trippy party effect. But you can also think of them as giving you the superpower of spectrometer vision, the ability to tell apart different kinds

The microscopic fractured edge of a piece of semiconductor looms like an enormous cliff face. However, this entire view would fit easily inside the diameter of a single human hair. At the top of the cliff is a rough dark layer, the remains of a protective layer that we bombarded

This is what an ordinary coffee shop looks like through diffraction glasses, which act like prisms to separate white light into a rainbow of colors. In this shot, you can see that not all white sources are alike - a few of them produce a continuous rainbow of colors, while

A rare view of the entire cross-section of one of my samples, which seems to loom like a massive iceberg over choppy seas. This sample is a thin layer of semiconductor (a material we use for making lasers, among other things), bonded to a much thicker chunk of glass. The

Fracture patterns at the edge of a broken wafer (broken on purpose, for once). The lighter top layer is silicon, and the darker bottom layer is glass. The glass looks darker than the silicon because it’s a better electrical insulator - the electron beam microscope makes an image by
