TR - Experiment at ICFO

Do you want to come to ICFO to experiment with photonics?
Choose one of the following activities: you will learn new things about light through hands-on activities designed for a small group of up to 3 students.
Each activity lasts approximately two hours.

  • Michelson interferometer
    This kind of interferometer was designed more than one hundred years ago to find the answer to one fundamental question of physics: is the space completely empty or filled with ether? More recently, in 2015, they used this same kind of interferometer to observe gravitational waves for the first time. In this activity, you can build a Michelson interferometer and eventually use it to measure the laser wavelength or the refraction index of some material.

  • Measure with a laser
    Lasers are very versatile tools that are at the core of many present technologies: that's one of the reasons why photonics is so important for our lives. In this activity you can use a laser to measure very small things like the diameter of a hair or the size of the holes in a CD. You can also measure the distance of an object.

  • Schlieren camera
    A Schlieren camera allows us to see changes in the refraction index that are impossible to see with our bare eyes. In this project you can learn how to build one and see the invisible.

  • Optical fibers
    Optical fibers are at the core of the internet as we know it now: if we hadn't these channels to transport light from one corner to the other of our planet, we wouldn't be able to exchange information so rapidly. With this activity you can learn how to put light into a fiber.

  • Graphene
    Graphene is an amazing material. This 2D material has a one-atom thick carbon structure that is 200 times stronger than steel, but is at the same time transparent and very light, presenting extraordinary electrical and thermal properties. This assures a brilliant future for this technology.
    In this activity, you can make some graphene and then observe it with the microscope.
