摘要： A small Faraday rotator is placed in the inner space of a receptacle and a holder. Because the plane of polarization is rotated, even when backreflection light returns to a laser diode, the lasing state does not become unstable. Being placed in the inner space and fixed there, the Faraday rotator can be small and therefore does not increase the part cost notably. The assembly cost does not increase, because it is not required to tightly press-fit a member into a narrow hole.
摘要翻译：一个小的法拉第旋转器放置在容器和支架的内部空间中。由于偏振面旋转，即使后反光回到激光二极管，激光状态也不会变得不稳定。放置在内部空间并固定在那里，法拉第旋转器可以很小，因此不会显着增加零件成本。组装成本不增加，因为不需要将构件紧密地压配合到狭窄的孔中。

摘要： An optical communications module in which electrical crosstalk is reduced. The term “optical communications module” represents a surface-mounting-type optical tranceiver, transmitter, or receiver module. The optical communications module has a following structure. (a) An Si substrate carries at least one signal-transmitting section comprising an LD, at least one signal-receiving section comprising a PD, or both together with other components. (b) An insulating substrate is bonded to the back face of the Si substrate. (c) A separating groove separates the Si substrate along the or each boundary line between the sections in order to prevent an AC current flowing through the Si substrate. To attain this object, the separating groove is provided from the top surface of the Si substrate to some midpoint of the insulating substrate. This structure reduces the electrical crosstalk between the signal-transmitting section and the signal-receiving section, between the signal-transmitting sections, and between the signal-receiving sections.

摘要： A jointing holder for an optical module for single-fiber bidirectional communication comprises a unitarily structured cylindrical body that has the following portions: (a) an optical fiber-fixing portion for securely holding an optical fiber for transmitting multiwavelength light bidirectionally, (b) a semiconductor laser-fixing portion for securely holding a semiconductor laser for emitting outgoing light λ 1, (c) a photodiode-fixing portion for securely holding a photodiode for receiving incoming light λ 2, (d) an optical path-forming space for optically coupling the optical fiber, the semiconductor laser, and the photodiode, and (e) in the optical path-forming space, an optical filter-fixing face for securely holding an optical filter for separating multiplexed wavelengths. The jointing holder enables the optical module to reduce the number of components, to be miniaturized, and to reduce the dimensional deviation at the time of the assembly, enabling high-precision assembly. An optical module for single-fiber bidirectional communication incorporates the jointing holder.

摘要： A standard multichannel optical fiber has a pitch 250 &mgr;m (P1), whereas mounting of optoelectronic device chips can require a pitch P2 larger than P1. The pitch of element fibers should be enlarged for coupling a multichannel ribbon fiber to a multichannel photodiode (PD) or laser diode (LD) module having photodiodes or laser diodes for M channels. The module includes a connector maintaining M fibers with tails extending backward and a bench having M V-grooves aligned at the larger pitch P2 for receiving the tails of the fibers. M light waveguides are aligned at the pitch P2 following the V-grooves. The module also includes M photodiodes or laser diodes following the light waveguides. A package includes the connector at a front part, the fiber tails at a width enlarging region for converging the pitch from P1 to P2, and the bench at a back part.

摘要： A bi-directional optical module with an improved optical crosstalk between the transmitter unit and the receiver unit is disclosed. The optical module provides the LD, the PD, the WDM filter secured with the block, and the package with the co-axial shape. The block provides a slant surface, where the WDM filter is secured thereon, the bottom surface facing the PD mounted on the package, and an aperture connecting the slant surface and the bottom surface. The PD is enclosed within a space formed by the bottom surface and the primary surface, which electrically and optically isolates the PD from the LD.

摘要： The present invention provides an optical receptacle that reduces the fluctuation of the optical coupling efficiency with the optical plug. The optical receptacle of the invention comprises a stub with a filler therein and a sleeve assembly to receive the optical plug. The stub with a cylindrical shape has an opening in the side where the optical plug is to be in contact thereto and a bore in the other side. The diameter of the opening is comparable to that of the core of the external fiber, while the diameter of the bore is greater than that of the opening. The filler exposes in this opening to couple with the external optical fiber. Thus, the optical coupling efficiency between the filler and the external fiber may enhance and the fluctuation thereof due to the insertion/extraction of the optical plug can be reduced.
