We show that the transmittance of light through waveguides is analogous to the conductance of electrons through mesoscopic wires only when a quasi-monochromatic light source is used. We also show that when casting the Maxwell equations into a Schrödinger-type equation in an optical waveguide with a spatially varying dielectric function ε{lunate}(ω,r) (the optical of a mesoscopic electron conductor with disorders), a velocity-like, non-hermitian term in the effective Hamiltonian prevails. The latter distinguishes the optical case from the electron case, in addition to the vector nature of electromagnetic waves.
