Optical interferometers, are very useful in various fields, where requiring precise wavelength tuning. Interferometers can amplify certain wavelengths with constructive interference and attenuate the rest, and can act as a wavelength filter. One of the well-known optical interferometers is the Fabry Perot cavity. In this study, an electrically adjustable optical filter is provided by integrating the Fabry Perot interferometer with two DBRs. DBR mirrors are 5 periodic layer with refractive index 2.1 and 1 respectively. The electrostatic part of the structure is a comb drives which supplied from 0 to 4 volts to change the cavity length, thereby tuning the center wavelength in the range 1400 to 1920 nm, and the adjustable range 520nm achieved.
