The present invention is related to the vertical cavity laser (VCL) that bind to the lattice mirror reflectance control for adjusting the laser output. Cavity (cavity) is, p- and n- bottom mirror formed by periodic refractive index grating region in the layer structure including a doped semiconductor layer, the active region and the outcoupling top grating having the electro-optical substance layer arranged there, It is formed by a mirror. Grating region comprises a lattice structure formed by the periodic perforated for varying the refractive index periodically in the vertical direction to the oscillation axis. The control voltage, in order to control the refractive index of the electro-optical material layer is applied to the reverse bias voltage between the n- and p- doped layers, whereby the refractive index spectrum of a grating mirror is controlled by. The reflectivity of the grating mirror is out of the coupling may be little or no adjustment between the reflectivity and the normal reflectivity having outcoupling, is assisted by both the VCL goaheun laser to the first and the second reflectance. Because the outcoupling mirror is to control the output laser light emission does not need to be adjusted, the present invention provides the advantages of low power consumption under a high control speed.
