Modelling the Mode Behavior of Circular Vertical-Cavity Surface-Emitting Laser

초록

영어

The design characteristics of circular vertical-cavity surface-emitting lasers are studied by using a newly developed equivalent network.. 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 is also utilized. This approach dramatically reduces the computational time as well as gives an explicit insight to explore the optical characteristics of circular vertical-cavity surface-emitting lasers (VCSELs).
