A Novel Equivalent Network Approach of Planar Vertical-Cavity Surface-Emitting Lasers

The resonance properties of vertical-cavity surface-emitting lasers have been studied by using a newly developed equivalent network based on the Floquet's theorem and the bisection principle. Optical parameters, such as the stop-band or the reflectivity of periodic mirrors and the resonance wavelength, are explored for the design of these structures. To evaluate the differential quantum efficiency and the threshold current density, a transverse resonance condition of modal transmission-line theory had been utilized. This approach dramatically reduced the computational time and it gave an explicit insight to explore the optical characteristics of vertical-cavity surface-emitting lasers (VCSELs).
