Paper Abstract

Vertical-cavity surface-emitting lasers (VCSELs) with single-mode, single-polarization emission at a wavelength of 894.6 nm was demonstrated for miniaturized atomic clocks. Utilizing the direct-etched surface grating on the surface of VCSELs, the state of polarization of VCSELs was controlled and pinned over the whole current range. The Modal properties of VCSELs with grating structures was studied using a finite difference time domain (FDTD) method. We investigate modal loss behavior with respect to the variation of grating structural parameters for the optimization of VCSELs polarization characteristics.
