IDIL fiber stretchers and piezo drivers are all developed and manufactured in-house. Each system can operate independently – indeed, our fiber stretchers do not require proprietary drivers and our piezo drivers are suitable with all fiber stretchers available on the market. Their compact packaging makes them suitable for various system applications. Typical applications include variable optical delay, fiber interferometry, ultra-fast dynamics and lasers.
For linear models (low frequency), a short length of fiber is fixed on a piezoelectric stack. For high frequency models, several meters of fiber are winded around a round PZ element. Applying a voltage to these elements will extend the PZ dimension and stretch the fiber. The higher the voltage, the higher stretching. The modulation bandwidth is limited by the capacitive effect of the PZ element. Driver specifications have to be chosen properly in accordance with the final application (frequency vs. depth of modulation). At a first order, we can consider the fiber elasticity is not type dependent; in other words, we can stretch any type of fiber while taking care of crucial specification like the insertion loss, the PER (for PM fiber), etc.
Time delay variations of +/- 20% may appear between each component

No more worrying about capacitive PZ values, driver deliverable current, etc. ; with combos, your 0-5V input modulation signal is directly translated into optical path length modulation and therefore into optical and phase delay.
The LF Combo is ideal for application using specific and expensive optical fiber types. LF stretchers are unique as they only require 20mm (FS 20µm) or 40mm (FS 40µm) of internal fiber length. They also offer ultra-low insertion loss < 0.05dB and are compatible with a large range of optical fibers (SM, MM, PM) and wavelengths from UV to IR.
The HF Combo is ideal for high-speed, fast feedback loop, interferometric and sensing applications. HF stretchers are the faster models available and offer enhanced signal modulation. They also offer low insertion loss < 0.3dB and are compatible with most of optical fibers (SM, MM, PM) and wavelengths from Vis to IR.
The HD Combo is ideal for large delay and high-speed applications. HD stretchers can reach up to 0.05ps time delay (100µm) at 1550nm. They also offer low insertion loss < 0.3dB. They are compatible with only SM and PM optical fibers at 1310 and 1550nm.
