    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: An optical waveguide is comprised of an optical substrate and an optical thin-film optical waveguide layer and formed such that ##EQU1## where .theta. is an output angle, n.sub.o1 is an ordinary refractive index of the optical substrate for an ordinary beam, n.sub.e1 is an extraordinary refractive index of the optical substrate for an extraordinary beam, n.sub.o2 is an ordinary refractive index of the optical thin-film optical waveguide layer for the ordinary beam and n.sub.e2 is an extraordinary refractive index of the optical thin-film optical waveguide layer for the extraordinary beam, and an electrode for generating a surface acoustic wave for diffracting light is formed on the optical waveguide to construct a collinear optical deflector. 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.
