摘要： A transmission line with a bending portion is provided, which line comprises any one of a coplanar line, another coplanar waveguide line formed on the dielectric substrate under which a ground layer is provided and a coplanar strip line. A chamfered portion is provided on the outer angular portion of the bending portion of the signal wiring conductor and a triangular conductor is disposed to an inner angular portion thereof. Given that length of the chamfered portion is defined as a, and length of the wiring edge side of the triangular conductor is defined as b and width of the signal wiring conductor is defined as c, it is arranged such that a is greater than b+c×square root of 2. Thereby, a transmission line or an optical module of smaller reflection loss at the bending portion thereof and of improved high-frequency characteristics is provided.

摘要： A PD (20) is mounted to a position offset (23) as viewed in the direction orthogonal to the center of an optical axis (14) of backward light (13) of an LD (11) in such a manner that a light receiving plane (21) thereof becomes substantially parallel to the center of the optical axis. Alternatively, the PD (20) is mounted thereto so that the light receiving plane of the PD is inclined at angles ranging from about 0° to about 30° to the center of the optical axis of the backward light. Further, the PD whose side face on the LD side is inclined, is used to repeatedly reflect the backward light between the PD and an LD mounting substrate, after which the backward light is launched on the light receiving plane 21. An optical module equipped with a PD for monitoring optical output power of an LD can be applied even to a junction up LD which reduces the number of parts, reduces even the number of connections by solder or the like and the number of electrical connections by wire bonding or the like, and makes no use of a base for the PD. Thus, low-cost PD mounting can be realized.
摘要翻译：从与LD（11）的反光（13）的光轴（14）的中心正交的方向观察，PD（20）被安装到位置偏移（23），使得光接收平面（21）变得基本上平行于光轴的中心。或者，PD（20）安装在其上，使得PD的光接收平面相对于向后光的光轴的中心约0°至约30°的角度倾斜。此外，LD侧的侧面倾斜的PD用于反复反射PD与LD安装基板之间的反光，然后在光接收面21上发射反光。具有用于监视LD的光输出功率的PD可以甚至应用于结合上LD，其减少部件的数量，甚至通过焊料等减少连接的数量以及通过引线接合等的电连接的数量，并且不使用PD的基础。因此，可以实现低成本的PD安装。

A method for production of the optical thin-film optical waveguide layer is exemplified wherein a target made of tantalic lilthium niobate or tantalic lithium niobate magnesium and an optical substrate made of lithium tantalate are prepared and an optical thin-film optical waveguide layer having a composition of tantalic lithium niobate or tantalic lithium niobate magnesium is formed on the optical substrate through an ion beam sputtering process into which oxygen can be introduced. Proton substitutes for part of an element constituting the optical thin-film optical waveguide layer.
