Lab

Each bench is a 3D model built from real catalog parts, with the physics worked out underneath. Drag things, change settings, read the numbers. On a phone, the simplified versions are coming; for now these work best on a laptop.

Ray tracing on a real bench

Ray tracing on a real bench

Ø2″ lenses on a rail: the ray-diagram rays traced through real glass, real images on a screen.

Mode converter

Mode converter

Lock a triangular cavity to one beam shape, then turn it into a donut beam with two cylindrical lenses, the idea behind my PhD work on LIGO mode matching.

Rainbow machine

Rainbow machine

Sunlight on a sun-tracking breadboard: a prism stripe and a one-ball rainbow ring.

4f lens system (Fourier optics)

4f lens system (Fourier optics)

Two lenses and a filter in the Fourier plane: erase a mesh, keep only the edges.

simulation
Cavity alignment trainer

Cavity alignment trainer

Walk the beam through two targets, retro-reflect, and flash the cavity modes into a clean TEM₀₀.

Imaging a Bell test with entangled photons

Imaging a Bell test with entangled photons

Entangled photons from a BBO crystal: a phase object on one, a filter on the other, and a Bell violation in the camera image.

Squeezed light

A bow-tie OPO and balanced homodyne detection push quantum noise below the shot-noise floor.
