Abstract: A THz-wave generator according to the present invention includes a nonlinear optical crystal 1 capable of parametric generation, a first laser device 12 for injecting a single-frequency first laser beam 7 as a pump wave into the nonlinear optical crystal, and a second laser device 14 for injecting a different single-frequency second laser beam 8 to thereby injection-seed a second laser beam 8 in a direction in which an idler wave is generated by the pump wave. By this configuration, it is possible, in generation of a THz-wave by use of the parametric effect in the nonlinear optical crystal under a non-collinear phase matching condition, to greatly increase a power of the THz-wave, to narrow its spectrum width, to make variable the wavelength of a generated THz-wave, and to hold its generation direction almost constant.

Abstract: The invention relates to a tuneable optical grid-assisted add/drop filter in codirectional mode of operation, which has the structure of a directional coupler filter with at least two adjacent waveguides having different refractive indices. The inventive filter must exhibit a spectral bandwidth of the filter transmission curve in the range from 50 GHz to 400 GHz for a high resolution in order to be tuneable and it must be producible in a more straightforward and more cost-effective manner, with dimensional tolerances higher than those of InP based add/drop filters. For that purpose, the material of the two waveguides is composed of two different classes of materials having different optical parameters. The thermal refraction index coefficient dn/dT, the electro-optic coefficient dn/dE or the dispersion dn/dnull of these two materials differentiate from each other in such a way that, in case of an action carried out upon the two waveguides with the same technical means with a view to changing the temperature, the electric field or the wavelength, effects with different strength occur and therefore, means for changing these parameters are provided. A polymer and silica are used as wave guide materials arranged vertically or horizontally relative to each other. For changing the optical parameter dn/dT, a device for modifying the temperature is used to influence the whole surface of a chip which contains the filter, said device being possibly identical to a device fore stabilizing the chip temperature.

Abstract: An optoelectric component has two waveguide layers and a layer with a periodic structure, which layers are arranged parallel to one another and are dimensioned so that a codirectional coupling is produced between modes guided in each of the waveguide layers. In order to prevent undesirable reflections, changes in the effective refractive index in the periodic structure is gradually changed along the direction of propagation. This change can be by the boundary of the periodic structure extending at an angle other than a right angle to the direction of propagation, either in a vertical or a lateral direction. The change can also be accomplished by a gradual change of the composition at the boundary of the periodic structure and adjacent portions or sections.

The interference layer (18) is supported by a lower cladding layer (16) deposited on a semiconductor substrate (12), a and Light travels through the core layer and is coupled into the interference layer by a grating.

Abstract: An optical apparatus consisting of a laser for producing a coherent polarized beam of electromagnetic radiation of a preselected wavelength. A substrate of silicon has a first transparent cover layer for receiving the polarized beam substantially normally incident thereto, an a second transparent guide layer for receiving the polarized beam from said first layer and for supporting at least one resonant mode. The first and second layers have a preselected index of refraction and a grating is interposed between them, having a grating period less than half the preselected wavelength. The layers and grating interact to produce a standing wave resonance by Bragg reflection. A control obtains a resonance wavelength in the guide layer equal to the predetermined radiation wavelength and thereby high reflectance to modulate the polarized beam.

Abstract: A controllable, electro-optical grating coupler for the optional switch-over or modulation of optical waves in waveguides includes a substrate with a first areal electrode arranged on the substrate and a first dielectric layer arranged on the electrode and carrying a waveguide. A periodic grating structure is arranged in the waveguide transversely to the direction of propagation of light and either the grating structure of the waveguide consist of electro-optical material in the region of the grating structure. A second dielectric layer is arranged on the waveguide and a second areal electrode is arranged on the dielectric layer. By varying the voltage across the electrodes it is possible to amplify or reduce the interference provided by the grating structure so that the light in the waveguide is modulated, switched, scattered from the waveguide or input coupled to a second waveguide.
