Interferential optics

Thanks to interferential optics, we can set up:

• Fabry-Pérot interferometers

• Mach-Zehnder interferometers

• Michelson interferometers

Which contain optical Microsystems.

Fabry-Pérot interferometers are made of membrane multilayer structures in which the mechanical or electromagnetic actuation of the suspended membrane movement enables modifying the length of a light optical path in order to change the length spectrum array of the light transmitted.

We can also make arrays of Fabry-Pérot interferometers, in particular to cover wider spectral regions.

The other types of interferometers can be set up in integrated optics and use directional couplers, of which disruptions brought to the various arms make it possible to change the incoming wave phase states in the coupler so the output interference pattern evolves.
