Abstract :
We present optofluidic fiber intensity modulator based on shaped and metal coated liquid core optical fiber filled with Cargille liquid. Static attenuation of 60 dB was achieved by thermo-optical effect, where focused laser beam was used as a local heating source. Different attenuation level can be simply adjusted using low optical power of heating laser. Dynamic response documents 30 ms response time.
