    Abstract: Provided is a resonant reflective filter including a substrate and a grating layer, wherein the substrate is formed of a material having a lower reflective index than that of a material forming the grating layer. Thus, the resonant reflective filter can form a resonant spectrum having good symmetry and a sharp shape. Accordingly, the resonant reflective filter can have improved sensitivity and can be applied to optical systems that require a small linewidth.

    Abstract: An electro-optic modulator is formed on a silicon-on-insulator (SOI) rib waveguide. An optical field in the modulator is confined by using an electrically modulated microcavity. The microcavity has reflectors on each side. In one embodiment, a planar Fabry-Perot microcavity is used with deep Si/SiO2 Bragg reflectors. Carriers may be laterally confined in the microcavity region by employing deep etched lateral trenches. The refractive index of the microcavity is varied by using the free-carrier dispersion effect produced by a p-i-n diode formed about the microcavity. In one embodiment, the modulator confines both optical field and charge carriers in a micron-size region.
