Calculating reflection of light when the refractive index changes
WebA semiconductor laser diode has an active area of length L = 500 m and a refractive index nsc = 3. The cavity mirrors were coated with anti-reflective material to improve performance. Calculate: a) If the net gain per unit length threshold is g = 113 cm-1, what is the value of the reflectivity of the mirrors of the diode? Web26. jan 2024 · Conversely, we can say that the reflectivity of a material is directly proportional to its SRI. The SRI of any material is measured on a scale of 0 to 100. A solar reflective index is a specific case of the more general term refractive index. medial.branch block
