摘要： A port including a lens for coupling one optical element with another optical element. The lens includes a focusing lens surface that has optical power and a flat lens surface that has little or no optical power. The lens is typically aspherical and couples high angle rays emitted from a source and also introduces aberrations such that the image formed on the receiving optical element is not reflected back to the source optical element. A point is imaged as a spot. The port couples light between optical elements by slightly defocusing the source without impeding the efficiency of the port.

摘要： An optical focusing system for a MOPA device that produces an astigmatic optical beam that includes a pair of lenses for focusing the optical beam into a single mode optical fiber. The optical beam has separated first and second focal points of origin. The first lens is placed one focal length away from the nearest focal point of origin for collimating the light beam in the vertical plane of beam propagation, while focusing the horizontal plane of beam propagation down into the optical fiber. The second lens only has optical power in the vertical plane of beam propagation, and is disposed one focal length away from the optical fiber for focusing the collimated light into the optical fiber. The beam has a symmetric spot size and numerical aperture in both the vertical and horizontal planes of beam propagation at the point it coherently enters the single mode optical fiber.

摘要： A receive optical subassembly comprises a header assembly positioned inside an outer shell that interfaces with a receive optical fiber. The header assembly comprises an upper surface upon which one or more optical components can be mounted, the upper surface defined at least in party by a standard plane. The header assembly further comprises an angled surface that is angled with respect to the standard plane. The angled surface can comprise, for example, a sloped cavity stamped inside the header assembly, or an angled shim positioned on top of the header assembly upper surface. An optical receiver mounted on the angled surface receives an incoming optical signal but reflects at least a portion of stray optical signals away from the incoming optical signal.

摘要： An optical reflection device for filtering and spatially positioning individual optical channels or wavelengths. The device includes a plurality of optical members with reflective surfaces and at least one reflective layer located on the reflective surface of each optical member. In addition, the plurality of optical members are interconnected in a manner such that the reflective surfaces are oriented at predetermined slopes with respect to one another. Each reflective layer is configured to reflect a particular wavelength or channel. The plurality of optical members are interconnected in a manner that allows each optical member to reflect an individual channel at a unique angle with respect to the other optical members. This configuration allows the optical reflection device to individually reflect and filter channels that are dispersed from some form of dispersing member, such as a prism or a diffraction grating.

摘要： Improved optical devices and methods transmit optical images along elongate optical paths with relatively limited cross-sectional dimensions using an improved objective, relay, and ocular systems. In a first aspect, at least one intermediate image formed within an optical component, rather than being formed in a gap between optical components. In a preferred embodiment, a first intermediate image is formed within glass of the most proximal objective lens, with the first intermediate image extending axially along a curved image location within the glass. The last intermediate image may similarly be disposed within a distal lens of the ocular system. By making use of a first and/or last intermediate image disposed in this manner within a lens, endoscopes can exhibit a significantly larger Numerical Aperture than known endoscopes having similar cross-sectional dimensions. In a second aspect, the ocular system allows independent adjustment of diopters, magnification, X-Y positioning, and rotation orientation of the captured image while introducing minimal aberrations.

摘要： Micro-optic components such as multiplexer/demultiplexers are disclosed. In one example, a micro-optic MUX/DEMUX includes a substrate having upper and lower surfaces, and a reflective coating disposed on a substantial portion of the lower surface. Multiple micro-prisms are disposed on the substrate and are constructed and arranged to receive, as inputs, multiplexed data signals having components of different wavelengths, but to transmit, as outputs, only a selected component of the input multiplexed signal. An I/O micro-prism is configured to receive a multiplexed signal from an optical fiber. In operation, the I/O micro-prism receives a multiplexed optical signal from an optical fiber. This multiplexed optical signal is then passed to the array of succeeding micro-prisms, each micro-prism extracting a corresponding component of the input multiplexed optical signal and transmitting the extracted component, until only a single component remains. The single component is then transmitted by the last micro-prism in the array.

摘要： Optical devices and related methods are provided. One example of the optical device includes two or more optical members joined together to form a stack. Each of the optical members in the stack includes a reflecting surface that has a corresponding slope, where the slope of each reflecting surface is different. In addition, disposed on each reflecting surface is a material that is reflective for a particular wavelength of light, so that each optical member reflects a different wavelength, and so that the optical members in the stack are able to collectively image the reflected signals onto a two dimensional detection plane.

摘要： An improved monitoring and control system for a laser in a header assembly of a transmitter optical subassembly (“TOSA”) is disclosed. The monitoring and control system, includes one or more monitor photodiodes (“MPDs”), is positioned together with the laser on a component submount. The submount in turn is mated with a multi-layer platform (“MLP”) that forms part of the header assembly. The MLP hermetically extends through the header assembly to provide a plurality of electrical interconnects for the laser, MPD(s), and other submount components. In one embodiment, a single MPD is located proximate the laser to receive back facet laser light emission. Measurement of the back facet emission enables the MPD to determine laser intensity. In another embodiment, two MPDs are joined together to receive the back facet laser light emission. Comparison of each MPD's measurement enables the laser's wavelength to be determined and adjusted to optimize its performance.
