“…In [1], the operating range of lters is the visible range (400 nm to 700 nm), in [2][3], the range is from 1500 nm to 1600 nm whereas the 1300 nm range is taken in [4]. Instead of using SiO, the air is sandwiched between two Silicon layers in [5] to realize three numbers of DeMUX for signal wavelength 1290 nm, 1310 nm, and 1330 nm by FDTD method where the thickness of Silicon and air is the decisive factor to decide the allowable wavelength. A modi ed Rowland grating structure is proposed in [6] to realize the optical lters which can be applied to design MUX/ DeMUX, detector array, multiple lasers, etc.…”

The control of the electrical system through a one-dimensional photonic crystal structure is realized in this paper. Here, the electrical system deals with the single-phase induction motor, where the photonic structure is manipulated with the silicon-based monochromatic optical filter. Further, the physics and mathematics of the proposed filter deal with the reflectance characteristics and plane wave expansion method respectively. Moreover, the principle of speed control in the induction motor relies on the simulation outcomes of the photonic filters which communicate the motor through a visible link using a microcontroller along with a ZCD (zero crossing detector) which decides the firing angle of the triggering circuit. Both, Matlab Simulink and physical implementation shows the nitty-gritty of the system which can easily be implemented in real-life application.
