    摘要: A reconfigurable optical add/drop module (ROADM) for dynamically adding or dropping various wavelengths of an optical signal without having to physically replace the module with a wavelength-specific add/drop module, and corresponding methods. A multiplexed optical signal in an optical network enters the reconfigurable optical add/drop module. Filters on the module separate various wavelengths of the optical signal along the module's various waveguides and a reconfigurable switching matrix directs the various wavelengths of the optical signal to be added, dropped and/or combined with other wavelengths.

    摘要: A means for optically coupling a semiconductor laser to an optical fiber is disclosed. In one embodiment, a volume phase holographic element is disposed on a light-emitting surface of a semiconductor laser. The volume phase holographic element acts as an aberration-corrector for a lens that is disposed between the semiconductor laser and the optical fiber. In this way, an inexpensive lens that is not aberration free can be used. In some embodiments, the volume phase holographic element converts a Gaussian light beam emitted by the semiconductor laser into an annular beam that is more suitable for long distance transmission in multimode fibers.

    摘要: Manufacturing coupling elements that have two or more ports. A focusing lens array is attached with a collimating lens array to form an element array such that each focusing lenslet is opposite a collimating lenslet. Optionally, an optical element such as a beam splitter is included between the focusing lens array and the collimating lens array. The individual coupling elements are then cut from the element array. After a row of coupling elements is cut or separated from the element array, a side of the exposed optical element can be polished and a third row of lenslets can be attached to the polished side of the optical element before the row is cut into individual coupling elements. This provides a third port to the coupling elements or optical transceivers.

    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: 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: Optical micro-modules include an integrated lens holder and microlens for passive coupling of optical signals into an optical fiber. The microlens includes a mounting surface and a curved section having an optical axis. The microlens curved section may be an aspheric silicon lens. The microlens mounting surface is attached to the lens holder mounting surface such that the microlens optical axis is centered with the optical fiber and aligned at a desired focal length from the optical fiber. The lens holder may, for example, be either in mechanical communication with a cable receptacle or be attached to a submount that has a silicon v-groove thereon for receiving an optical fiber. The optical micro-module may be part of other optical devices, for example a transmitter optical sub-assembly or a receiver optical sub-assembly.
