Fiber stretcher (femtosecond/micrometer range) / Optical delays

Our compact fiber stretchers (also called phase shifters) offer the attractive feature to modify the optical path from 0 to 0,1ps or 0 to 0.2ps.

Fiber stretcher (femtosecond/micrometer range) summary

The fiber is fixed on a multilayer piezoelectric actuator. The stretcher uses the piezoelectronic element to change the optical path and phase. IDIL Fibres Optiques phase shifters are available with all fiber types (SM, MM, PM) and offer a particularly fast and accurate technique.

Its compact packaging makes it suitable for various system applications. Typical applications include variable optical delay, fiber interferometry, ultra-fast dynamics and lasers.
