摘要： For each channel in a parallel channel optical array, a diffractive optical arrangement (DOA) includes an input region that is configured to pass a first portion of an input beam to an output region for data transmissions and to diffract and direct a second portion to a detection region for monitoring. The input region includes the diffractive features of a computer generated hologram (CGH) or a grating for diffracting. Alternatively, the input region is coupled to the CGH or grating. Moreover, the DOA includes at least one reflective region for redirecting the second portion. In one embodiment, the DOA includes a separate active surface for each channel of the array. Alternatively, the DOA has a singular active surface that is positioned to interact with all the channels. Optical power output from the second portion is monitored to generate feedback signals for adjusting the input current to each laser. Additionally, optical power output from sensed temperature is monitored to generate feedback signals.

摘要： A light transmission system includes a laser, an optical fiber, and a transfer lens. The transfer lens transfers light emitted by the laser into the optical fiber. The transfer lens includes a diffractive surface for receiving and collimating the light originating form the laser. The diffractive surface is defined by a surface function that includes a first phase function having angular symmetry and a second phase function having radial symmetry. The second phase function includes a cusp region with a discontinuous slope therein. The transfer lens provides reflection management so that light reflected from the end of the optical fiber is not focused at a location at which light is emitted by the laser and also favorable launch conditions so that light launched into the optical fiber avoids index anomalies along the axis of the optical fiber.

摘要： An optical coupler converts a light distribution from a light source into a small angle distribution that extends over a volume larger than the variations in the alignment of an optical fiber. In one embodiment, a diffractive or hybrid diffractive/refractive bifocal lens forms first and second images of the light source respectively in first and second image planes. An input face of the optical fiber is between the first and second image planes and receives light diverging from the first image plane and light converging toward the second image plane. The net optical power coupling into the fiber is uniform over a large range of fiber positions and provides the optical coupler with a relaxed tolerance for misalignment of the fiber or the light source. The relaxed alignment tolerance facilitates low cost manufacture of multi-channel optical transmitters using single-mode optical fibers.

摘要： Disclosed are various embodiments of systems, devices and methods for forming an hermetic seal between a lid and a submount for an electronics module or package. At least one thieving pad is connected to a metallized ring formed about or near the circumference of an upper surface of the submount. A corresponding metallized ring is disposed about the lower perimeter of the lid. Solder paste is placed between the two metallized rings and melted, preferably under a reducing atmosphere. Excess molten solder controllably flows towards the at least one thieving pattern while the lid is being hermetically sealed and soldered, avoiding the formation of undesired wayward solder balls inside the package.

摘要： An optoelectronic package or sub-assembly includes an edge-emitting laser and a reflector that directs a beam from the laser through a sub-mount. The sub-mount contains passive or active circuit elements that are electrically connected to the laser. The laser can be protected from the environment using either a cap in which the reflector is integrated or using an encapsulant encasing the laser. An alignment post that is sized to fit into a sleeve is mounted where the optical signal emerges from the sub-mount. Plugging the post into one end of the sleeve and inserting an optical fiber into the other end of the sleeve so that the optical fiber abuts the post will then align the optical fiber to receive the optical signal.

摘要： Disclosed are various embodiments of systems, devices, components and methods for launching high-transmission-rate optical communication signals into legacy fiber optic cables. At least one aperture is provided on a proximal end of single-mode fiber optic stub so as to block or otherwise control the propagation of unwanted light into and through the stub. In one embodiment, a low-cost spheroidal lens is mounted between the optical transmitter and the proximal end of the fiber optic stub to focus and direct light emitted by the optical transmitter towards the fiber optic stub. The relatively broad light beam formed by the low-cost lens, in combination with the aperture, removes the requirement to precisely align the transmitter, lens and stub with one another, and further does away with the conventional requirement to attenuate the amount of signal power provided to the fiber optic stub.

摘要： Methods and devices are provided for the extracorporeal ablation of target cells circulating in blood of an organism. Exogenous material introduced into the blood preferentially associates with target cells (e.g. cancer cells, bacteria, viruses) in the blood. An extracorporeal continuous flow pathway accesses the patient's blood to apply an external energy source to the blood at an ex vivo ablation device in a portion of the extracorporeal continuous flow pathway. The exogenous material interact with the applied energy so as to result in the damage or death of the target cells. The blood is then returned to the body in a continuous-flow pattern. By applying the energy while the blood is in the ex vivo ablation device, shielding of the target cells by the body is reduced and detrimental effects on the organs and tissues of the body are avoided or mitigated.

摘要： Compactness is preserved while enabling beam monitoring of optical properties of an output beam by employing a combination of reflection and diffraction. An input beam is reflected, divided using reflection/diffraction, and re-reflected. As a consequence, both a light source and one or more beam monitoring detectors may be disposed along a single side of an optical module. In one embodiment, an input beam is introduced from a first side of an optical module, is reflected by a 45 degree mirror, and is divided by a diffraction grating which redirects a minor portion of the beam energy back to the 45 degree mirror. Following the second reflection from the mirror, the returned portion of the beam is used to measure one or more optical properties.
