Abstract

In this erratum, we correct the mistakes in Eqs. (2) and (2a) in Opt. Lett. 45, 443 (2020). [CrossRef]

Equations (2) and (2a) in Ref. [1] should read

(1)$${I_{{\rm TE}}}(x) = {I_0}\left[ {1 + \cos \left(\frac{{4\pi {n_1}\sin {\theta _1}}}{\lambda }x \right)} \right]$$

and

(1a)$${I_{{\rm TM}}}(x) = {I_0}\left[ {1 + \cos (2{\theta _1})\cos \left(\frac{{4\pi {n_1}\sin {\theta _1}}}{\lambda }x \right)} \right],$$

respectively. Equation (3), which we use to calculate the peak intensity in the interference pattern for the TM polarization, is not affected by the mistakes in Eqs. (2) and (2a), and remains valid.
