摘要： An optical module for use in detecting a plurality of different wavelengths by making use of the multiple wavelength selectivity of an etalon. The optical module includes a semiconductor laser, a lens for converting a beam emitted from the semiconductor laser into a substantially parallel beam, a beam splitter for splitting the converted beam into a reflected beam and a transmitted beam, and a light-receiving element disposed such that one of the split beams is incident thereupon through an etalon, wherein a center of the reflected beam from the etalon occurring as the beam is incident upon the etalon is arranged to return to a region other than a beam-emitting portion of the semiconductor laser.

摘要： The present invention is related to an optical communication module for transmitting high frequency signals (e.g., 10 Gbit/s and higher data rates) between an optical element and an external circuit. In an illustrative embodiment, the optical communication module includes signal transmission lines and ground lines formed on a ceramic substrate, a flexible wiring board, and a printed circuit board. The widths of the signal lines and the ground lines vary, as well as the spacing between the signal and ground lines. This facilitates characteristic impedance matching among the signal lines to within about 50Ω.

摘要： A subject of the invention is to reduce the temperature dependence of an etalon as a wavelength locker for a semiconductor laser device and so forth. Concretely, it is to restrict the lowering of the wavelength locking performance of the etalon dependent on the temperature variation. A means to solve the subject is the use of an air gap etalon. Concretely, the means is provided with a media plate and parallel plane plates on both sides of the media plate. The two parallel plane plates and the space between them constitute the air gap etalon.

摘要： In anodic bonding between a conductor or semiconductor and glass, in order to attain good adhesion at a lower bonding temperature than usual and improve the toughness at its boundary to obtain higher reliability for a bonded portion even in a case where bonded members are warped or dust is present at the bonding boundary, a soft metal film is formed on the surface of a conductor or semiconductor on which an active metal film having high reactivity with oxygen is formed, whereby a warp or dust, if any, can be absorbed by the deformation of the soft metal film, thereby to improve the adhesion at the boundary. Adhesion at the bonding boundary is improved even at a low bonding temperature of, e.g., about 200° C. Further, the toughness at the bonding boundary can be improved to increase reliability by roughening the bonded surface on the side of the glass.

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.
