Find the quality factor of the lowest-order mode in part b

Question

1. An optical resonant cavity is implemented with two identical mirrors.

(a) Plot thc transmission (I_trans/I_line) through the cavity as a function of θ = kd.

{-1.5 Π < θ < 1.5 Π} for R=0.6, R=0.9, R=0.95, where R is the reflectance of the mirrors.

(b) Plot the normalized internal intensity (I_trans/I_line) and the transmission (I_trans/I_line) of the cavity for R=0.6, R=0.9, R=0.95 between λo = 500 nm and λo = 3000 nm. Assume that the refractive index of the cavity is ncavity = 1.001 + j 0.0001. Ignore the dispersion of the medium.

(c) Find the quality factor of the lowest-order mode in part (b).
