Abstract: (2984 Views)
In this paper, design and simulation of an optical filter based on Mach-Zehnder interferometer with a subwavelength grating waveguide (SWG) is presented. It is shown that the use of SWG in one of the Mach-Zehnder arms causes a significant difference in the refractive index between the arms and enables us to control the phase difference correspondingly. This eliminates the need for length difference between the arms and reduces the dimensions and the loss of the device. The designed filter has an extinction ratio of 28 dB, insertion loss of 0.3 dB, 3-dB bandwidth of 0.5 nm, and 12 nm free spectral range.
