Optical attenuator plays an important role in solving the problem of channel power balance
optical fiber system index measurement
and power matching of all optical networks.In this paper
based on the Gaussian beam propagation and diffraction field theory analysis
the distribution of shutter based variable optical attenuator’s internal light field is studied.Based on the rectangle
triangle
round three types of shutter
the shutter based optical attenuator is experimentally investigated.The shutter based optical attenuator’s theory results and experimental results are compared.It is shown that the triangle shaped shutter optical attenuator has the best performance.
