Polarization Properties of a Nano-Particle Array Grating on GaN-Based LED

Abstract:

A nano-particle array grating is proposed to achieve fine polarized output and transmittance on GaN-based LED. This nanostructure enables simple fabrication, since the novel arrays can be directly coated on the surface of GaN. In this letter, Aluminum nano-particle array gratings are optimized at blue and green band respectively. Extinction ratio up to 26dB and a TM polarized transmittance of 76% are achieved. Theoretical results show the nano-particle grating can be a guidance in designing the integrated GaN based and polarized photonic devices. Numerical simulations are performed using the Finite-difference time-domain (FDTD) solutions.
