Abstract: The optical device includes a waveguide on a base. The device also includes a modulator on the base. The modulator includes an electro-absorption medium configured to receive a light signal from the waveguide. The modulator also includes field sources for generating an electrical field in the electro-absorption medium. The electro-absorption medium is a medium in which the Franz-Keldysh effect occurs in response to the formation of the electrical field in the electro-absorption medium. The field sources are configured so the electrical field is substantially parallel to the base.

The method comprises masking steps of the thin layer of silicon to define therein the rib of the waveguide, etching of the rib, masking of the thin layer of silicon to delimit the parts to be doped P, doping of the parts to be doped P, masking of the thin layer of silicon to delimit the region to be doped N and doping of the region to be doped N. The masking steps utilizes a hard mask whereof the pattern defines the rib of the waveguide, the zone to be doped P in the rib of the waveguide and the limit of the doped region N relative to the rib of the waveguide.

Abstract: Described is a method of controlling the absorption of light in a cavity, a system in which absorption is so controlled, and an interferometer embodying the underlying physical concept. Materials can be made to completely absorb incident light when the light is imposed in a specific pattern of illumination. Coherent perfect absorption, as the process is referred to, is achieved when a cavity is illuminated coherently and monochromatically by the time-reverse of the output of a lasing mode. Varying the parameters of the incident light and/or of the cavity allows the absorption of the incident light by the cavity to be controlled; enhanced or even reduced.

Abstract: By introducing magneto-optical garnets with high Faraday rotation and low optical loss in a ring resonator, a nonreciprocal phase shift is generated to split the resonance wavelengths of clockwise and counter-clockwise modes under magnetic field. There are three main applications based on this nonreciprocal effect, optical isolators, optical circulators, and tunable optical filters. The concept of the tunable filters and the design of optical isolators for TE and TM modes are described in the paper. With proper optical ring isolator configurations, optical circulators can be realized.
