Abstract :
We present variable fiber optical attenuator based on shaped and metal-coated liquid core optical fiber filled with index matching liquid. Variable attenuation of 60 dB was achieved by thermo-optical effect, where focused laser beam with optical power of 2 mW was used as a local heating source. Dynamic response shows rise time of 30 ms.
