摘要： An optical modulator includes an optical waveguide, a modulating electrode, a conductive layer, an electric signal input section, and connector members. At least a portion of the optical waveguide is made of an electro-optic material. The modulating electrode includes a first conductor line and a second conductor line, which are coupled together electromagnetically, and applies a modulating electric field to a portion of the optical waveguide. The conductive layer forms a first microstrip line with the first conductor line and a second microstrip line with the second conductor line, respectively. Through the electric signal input section, an RF modulating signal is supplied to the modulating electrode. The connector members connect the first and second conductor lines together at both ends. In this optical modulator, the first and second conductor lines function as an odd-mode resonator for the RF modulating signal.

摘要： A dielectric resonator filter comprises dielectric resonators, an enclosure having a main body, a lid, and partition walls, interstage-coupling tuning windows, interstage-coupling tuning bolts, input/output terminals, and input/output coupling probes. Resonance-frequency tuning members each composed of a conductor plate and a bolt coupled integrally thereto are attached to the enclosure lid. Undesired-mode suppressing means such as rings attached to the bolts of the resonance-frequency tuning members or bolts attached to the conductor plates or to the enclosure lid are disposed in an undesired-mode excitation space, whereby the occurrence of a disturbed characteristic in the pass band (or stop band) is suppressed.

摘要： The resonator of the present invention includes a cylindrical dielectric and a conductor film covering the surface of the dielectric in close contact therewith. The conductor film is constructed of a cylindrical portion and two flat portions, and is formed by subjecting the surface of the dielectric to metallization or the like. With the conductor film formed in close contact with the dielectric, deterioration of the Q value and the like caused by instability of connection at the corners can be suppressed even when a radio frequency induced current flows from the cylindrical portion over the two flat portions.
