LabExT, short for Laboratory Experiment Tool, is a software environment for performing laboratory experiments on silicon-photonic devices and chips. The tool is free, written in Python 3.7 and uses the I/O API VISA through pyvisa.
- Execute pre-defined measurement routines using laboratory instruments at any VISA address.
- Measurement code and instrument driver code easily extensible via their API.
- Immediately investigate and plot the resulting data.
- A large set of meta-data is also recorded.
- Commenting on resulting data is immediately possible after measurement.
- Chip-scale automation with motorized stages.
- Supports coordinate files of on-chip devices and moves stages to correct locations (e.g. for coupling fibers to on-chip grating couplers).
- Local optical coupling optimization including Gaussian mode profile fitting.
- High Usability
- No Python coding knowledge necessary to execute lab experiments!
- Keyboard shortcuts!
Before losing too many words, check out the following video which demonstrates how we use LabExT in our daily work:

LabExT is written in part by tireless folks at the Institute of Electromagnetic Fields, ETH Zurich, Switzerland as part of their daily grind in an RF and optics laboratory.
Another big part is written by Polariton Technologies AG whose support and experience in integrated optics design and the testing thereof we gratefully acknowledge.
