摘要： Disclosed is a novel "hermetic" optical assembly. A radiation-transmissive member seals an aperture in the assembly housing. The member comprises two major surfaces and a recess that extends from one surface towards the other, with a "septum" between the bottom of the recess and the other surface. An optical or opto-electronic device typically is mounted on the inside surface of the member, and the end of an optical fiber is maintained outside of the assembly in coupling relationship with the device. In a currently preferred embodiment the recess extends from the outward-facing surface of the member and serves to position the end of the optical fiber with respect to a device mounted in a "well" in the inward-facing surface of the member. In another embodiment, the outward facing surface of the member comprises geometrical features (e.g., recesses) that mate with corresponding features (e.g., protrusions) on a guide plate that serves to position the ends of a multiplicity of fibers with respect to devices mounted on the bottom of a recess extending from the inward-facing surface of the radiation-transmissive member. In all embodiments radiation is transmitted through the septum. In preferred embodiments the radiation-transmissive member is (100) Si, with the recess (and other features) produced by means comprising photolithography and anisotropic etching.

摘要： An assembly for coupling an optical fiber to a light emitter or detector comprises a silicon block having features that make possible easy alignment of the emitter or detector with the end of the optical fiber. The features comprise a through-aperture with sloping walls that receives and positions the end of the fiber in a predetermined location, and precisely defined conductive features that serve as alignment markers in the placement of the emitter or detector.

摘要： A new method for fabricating optical assemblies (OAs), which achieves increased throughput and reduced unit cost by mass producing optical subassemblies (OSAs), is disclosed. In accordance with this method, at least two OSAs are simultaneously produced by initially forming at least two corresponding sets of electrically conductive regions on the surface of a substrate. At least two optoelectronic devices are mounted on the surface of the substrate, with each device in electrical contact with one of the two conductor sets. Afterward, the substrate is separated into at least two parts, with each part including one of the optoelectronic devices and one of the conductor sets, constituting an OSA. Each OSA is then incorporated into an OA.

摘要： The disclosed means for coupling an optical fiber and an opto-electronic device (e.g., LED, Laser, or photodetector) comprises a first body having two substantially parallel major surfaces, with a recessed portion (a "well") formed in one surface, and a through-aperture extending from the other surface to the well. Conductive means extend from the former surface onto the bottom of the well, and the opto-electronic device is to be mounted in the well such that the device does not protrude above the plane of the associated surface, such that electrical contact is established between the device and the conductive means, and such that the active region of the device is centered upon the through-aperture. The first body is advantageously from a (100) Si wafer by means of standard Si processing techniques, including selective etching. The assembly can be mounted on a substrate, e.g., a Si wafer with appropriate metallization thereon, and the end of an optical fiber inserted into the through-aperture and secured to the first body. The assembly can be operated at relatively high speed, due to its relatively low parasitic capacitance and inductance, and can be mounted on the substrate in substantially the same way as IC chips are mounted, in close proximity to associated electrical components.

摘要： An m-input/n-output (e.g., 2.times.2) optical fiber switch is disclosed which alters the location of the fibers by the application of an external force. Illustratively, the switch uses a housing with a diamond-shaped opening extending therethrough, with pairs of optical fibers positioned in orthogonally located V-grooves. Upon the application of an external force, the fibers are moved into the remaining, vacant V-grooves formed by the diamond-shaped opening. In a preferred embodiment, a (2.times.2) switch is magnetically activated.

摘要： A method for compensating for both material or chromatic dispersion and modal dispersion effects in a multimode fiber transmission system is provided. The method includes, but is not limited to measuring a fiber-coupled spatial spectral distribution of the multimode fiber laser transmitter connected with a reference multimode fiber optical cable and determining the amount of chromatic dispersion and modal dispersion present in the reference multimode fiber optic cable. The method also includes, but is not limited to, designing an improved multimode fiber optic cable which compensates for at least a portion of the chromatic dispersion and modal dispersion present in the reference multimode fiber optic cable resulting from the transmitter's fiber-coupled spatial spectral distribution.

摘要： A fiber optic connector having a double-clad specialty optical stub fiber with a deep index core-to-inner-cladding profile and a raised index outer-cladding profile. The double-clad optical stub fiber abuts against a single-clad field optical fiber of the single-mode type to form an interface across which the primary mode traverses without significantly interfering with higher-order modes. The ratio of the radius of the inner cladding to the radius of the core of the stub fiber is less than 6.5:1. The index profile of the refractive index of the inner cladding is deep relative to the refractive index of the core to confine the primary mode within the core. The raised refractive index of the outer-cladding pulls the higher-order modes deeper into that region, reducing interference with the primary mode. The respective core diameters of the field and stub fibers are matched to avoid mode-field diameter mismatch.

摘要： The present invention is a flexible plastic membrane which supports embedded components such as light emitting diodes and plastic pressure switches, and conductors on a plastic ribbon which connects the embedded light emitting diode and plastic pressure switch to a connector. The flexible plastic membrane supports an adhesive which enables it to be stick to the surface of the module face plate. The inventive structure is more economical to build and install than presently used mechanical spring loaded push switches and light emitting diodes as they must be physically mounted to the face plate and hardwired when the module is manufactured. In addition, the inventive structure can be replaced in the field when a fault develops without disturbing or disconnecting the optical fiber connected to the front or rear of a module.
