Calculate the normalized internal intensity

Question

Assignment:

An optical resonant cavity is implemented with two identical mirrors.

(a) Plot the transmission (I_trans/I_inc) through the cavity as a function of fi=kd.

{-1.5 π < 0 C 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_int/I_inc) and the transmission (I_trans/I_inc) of the cavity for R=0.6, R=0.9, R=0.95 between λ0 = 500 run and λ0 = 3000 inn. Assume that the refractive index of the cavity is n_cavity=1.001+ 0.0001. Ignore the dispersion of the medium.

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