The controlling of an electrical system through a one-dimensional (1-D) photonic crystal (PhC) structure using a laser beam is theorized in this paper. Here, the electrical system deals with the single-phase induction motor, where the PhC structure is accounted for Si-based structure through which a monochromatic laser beam is generated. Further, the physics and mathematics of the generation of laser govern the reflectance characteristics and plane wave expansion (PWE) method respectively. The principle of speed control in the induction motor depends on the simulation outcomes of the laser beams which communicate to the motor through a visible link using a microcontroller that is associated with a zero crossing detector (ZCD) which eventually decides the firing angle of the triggering circuit. MATLAB Simulink and explores the performance of the system to assess its implementation in real-life applications.
