Open publisher page 0 citations

Abstract

A multi-mode interference double wavelength optical power splitter was studied.The device can be used to divide beam for both 1.30 μm and 1.55 μm at the same time.The guided-mode propagation analysis method was used to analyze the working principle of MMI double wavelength optical power splitter.On the basis of predefined waveguide parameters,intsertion loss and imbalance of this device were also analyzed.The optimum width and wavelength of the multimode waveguide are 28 μm and 2 735 μm,respectively.The two insertion losses are 0.59 dB,0.41 dB and power uniformities are 0.16 dB,0.15 dB,respectively.
