We developed a micromechanically tunable vertical cavity surface emitting laser in which the polarization is controlled by metal slit. The slit was fabricated on a mirror in a microcavity, with the width of the slit being approximately the same as th

We have numerically calculated the stability diagram of the higher modes of the Fabry-Perot resonator by direct diagonalization of the Fox-Li equation. The diagram has an exotic behavior in the small Fresnel number region and its higher modes in our

The adhesion judgement formula of the mirror with clamped beams is derived by the theoretical and numerical calculation. In design phase of the MEMS structure, it is difficult to judge the structure adheres to the substrate or not except circle plate

The stability diagram of the Fabry-Perot resonator composed of two spherical mirrors is calculated by the Kirchhoff diffraction integral equation. We have derived the proper equation from the integral and diagonalized it. It has also been calculated
