The optical component comprises an optical device chip including an LN waveguide, a first PLC waveguide, a second PLC waveguide, and a fiber alignment member, a mount, and optical fibers. Each of connection faces between the first PLC waveguide and the fiber alignment member is configured as a tilted structure, and each of connection faces between the LN waveguide, and the first and second PLC waveguides is configured as a right-angled structure. In the right-angled structure, the connection faces are connected by an adhesive having a lower Young's modulus than that of an adhesive used on the connection faces of the tilted structure.

In an optical component (500), a first planar lightwave circuit (501) having a first refractive index n 1 and a second planar lightwave circuit (502) having a second refractive index n 2 different from the first refractive index n 1 are butt jointed on the end surfaces thereof perpendicular to an optical axis direction. First to n-th optical waveguides (where n is an integer greater than or equal to 2) are formed on each of the first and second planar lightwave circuits. The first and second planar lightwave circuits are aligned and jointed such that the position of an i-th optical waveguide (where i is an integer greater than or equal to 1 and less than or equal to n) of the first planar lightwave circuit and that of an i-th optical waveguide of the second planar lightwave circuit are matched on a joint interface. An angle Õ i formed by the i-th optical waveguide of the first planar lightwave circuit and a normal of the interface is configured to vary in accordance with a value of i within a range satisfying the Snell's law.

摘要： Provided is an optical modulator that suppresses a chirp generated during phase modulation by a shift in position of a pn-junction caused by mask misalignment or the like and provides a high-quality waveform. The optical modulator is provided with two RF electrodes for applying a pair of differential signal voltages, at least one fixed potential electrode for applying a fixed potential, a first conductive semiconductor layer and a second conductive semiconductor layer in contact with the RF electrodes or the fixed potential electrode, and an optical modulation unit in which two optical waveguides that branch out from one optical waveguide and are arranged along a pn-junction part that forms a boundary between the first and second conductive semiconductor layers are formed. The optical modulator is characterized in that the semiconductor layers and the electrodes are arranged so that the integration amount of phase changes caused by deviation of the position of the pn-junction part in the two optical waveguides from a design value becomes equal between the two optical waveguides.
