摘要： A high frequency optical modulator ( figure 2 ) based on an electro-optic material (such as LiNbO 3 ) is provided with separate connection (20) and termination substrates (21) for applying the external microwave modulation signal (6) to the signal electrode (2) of the modulator. Light passing through an optical waveguide formed on the electro-optic material is modulated according to the signal from the signal electrode.
However, noise in the microwave signal produces jitter in the modulated optical output, degrading the modulator's characteristics.
Specifically, radiation modes (24) originating at the input terminal (22) of the connection substrate can cause noise at its output terminal (23), which is connected to the signal electrode of the modulator; while radiation modes (26) produced on reflection at the termination device (9) on the termination substrate (21) can cause noise at its input terminal (25), which is also connected to the signal electrode of the modulator; both effects contribute to modulator noise.
Substrate radiation modes (24,26) are prevented from reaching the substrate terminals (23,25) connected to the signal electrode of the modulator, (i) by arranging the respective substrate input / output terminals not to lie in the propagation regions of radiation modes ( figure 2 ); or (ii) by employing radiation mode shielding means (55) or deflecting cavities (66) in front of the terminals connected to the signal electrode of the modulator.

摘要： A technology to automatically control the biasing of an optical duobinary transmitter using a single-drive LN-MZ modulator is provided. A low-frequency signal is amplitude modulated onto a voltage signal input into a Mach-Zehnder optical modulator 22. The optical output from the optical modulator 22 is detected by an optical detection subsystem 30. In a bias control subsystem 40, the low-frequency signal component amplitude modulated onto the electrical signal is detected from the optical output, and a DC bias voltage applied to the optical modulator is controlled such that the low-frequency signal component is either minimized or maximized.

摘要： An optical wavelength converting device is provided with a LiTaO3 substrate, a plurality of inverted-polarization layers periodically arranged in an upper surface of the LiTaO3 substrate, and an optical waveguide crossing the inverted-polarization layers. The upper surface of the LiTaO3 substrate is directed toward a -X-crystal axis direction. The inverted-polarization layers are formed by exchanging Ta ions of the LiTaO3 substrate for H ions, and an extending direction of each inverted-polarization layer is inclined at an angle of theta degrees (6 ions of the LiTaO3 substrate and the inverted-polarization layers for H ions to set a refractive index of the optical waveguide higher than that of the LiTaO3 substrate. The optical waveguide extends in a +Y-crystal axis direction. Fundamental waves polarized in a transverse electric mode induce electric field directed in +/-Y-crystal axis directions and are converted into second harmonic waves in the optical waveguide.
