摘要： A wavelength converter implements high speed, high efficiency, low noise wavelength conversion without performing high voltage poling of a crystal, and enables switching and modulation of converted light in response to an electric field. A KLTN crystal, includes a deposited-gold electrode within its incidence plane, and is connected to a DC power supply via a copper wire. The crystal material is composed of KTa1-xNbxO3 and/or K1-yLiyTa1-xNbxO3. A polarizer controls the polarization of the fundamental wave in the direction parallel to the electric field, and launches it into the electrode of the KLTN crystal. The KLTN crystal, rotating on an axis in the direction of the electric field, launches only part of the generated SHG light with the same polarization direction as that of the incident light into a photo multiplier tube through a polarizer.

摘要： An optical waveguide capable of having various characteristics and a method of manufacture thereof as well as a method of manufacturing a crystal film are provided. An optical functional material KTaxNb1-xO3 is used as an optical waveguide. The input optical signal is transmitted to the KTaxNb1-xO3 film. The KTaxNb1-xO3 film undergoes changes in optical property when an external voltage signal is applied to the electrode. Therefore, as it passes through the KTaxNb1-xO3 film, the input optical signal is modulated by the characteristic change. The modulated optical signal is taken out as an output optical signal.

摘要： A laser light source is disclosed consisting of first and second lasers that respectively generate laser beams of wavelengths λ1 and λ2. Wavelength λ1 is in the range of 0.9-1.0 μm. A nonlinear optical crystal uses the laser beams of wavelengths λ1 and λ2 as inputs, and outputs a coherent beam having a wavelength λ3 of a difference frequency that satisfies a relationship of 1/λ1−1/λ2=1/λ3. The nonlinear optical crystal has a periodically poled structure of a single period. The wavelength λ3 of the difference frequency varies between 3.1 μm and 2.0 μm when the wavelength λ2 varies between 1.3 μm and 1.8 μm.
