Description

This lecture discusses the refraction of light in a three-dimensional scenario, focusing on the emission efficiency of a point on a PN junction. The instructor explains the calculations involved in determining the light yield and emission efficiency, considering the refractive index of the GAAS layer and the total reflection angle. Through a detailed analysis of the light flux and area calculations, the lecture provides insights into the transformation of a two-dimensional figure into a three-dimensional representation, emphasizing the importance of considering the angle of refraction. The lecture concludes with a practical example involving the refractive index of GAAS, leading to the determination of a specific value for emission efficiency.
