Abstract

The article focuses on an innovative experimental setup designed to simultaneously demonstrate the wave–particle duality of light (LWPD) for undergraduate optics students. Utilizing optical radiation pressure from a 980 nm laser to trap and manipulate microparticles, the setup reveals the particle nature of light, while dual-beam interference of a 1550 nm laser reflected from both the fiber probe and trapped particle verifies its wave nature. This fiber-optic-based system is low-cost, resistant to external interference, and easy to assemble, providing students hands-on experience with modern optical instruments and enhancing their understanding of LWPD concepts. Student feedback from the experimental class indicates high satisfaction and increased interest in optics and related scientific research.
