摘要： An optical device for rerouting and modifying an optical signal that is capable of operating as a dynamic gain equalizer (DGE) and/or a configurable optical add/drop multiplexer (COADM) is disclosed. The optical design includes a front-end unit for providing a collimated beam of light, an element having optical power for providing collimating/focusing effects, a diffraction element for providing spatial dispersion, and modifying means which in a preferred embodiment includes one of a MEMS array and a liquid crystal array for reflecting and modifying at least a portion of a beam of light. The modifying means functions as an attenuator when the optical device operates as a DGE and as a switching array when the optical device operates as a COADM. Advantageously, this invention provides a 4-f system wherein a preferred embodiment the element having optical power is a concave reflector for providing a single means for receiving light from the front-end unit, reflecting the received light to the dispersive element, receiving light from the dispersive element, and providing dispersed light to the modifying means. Conveniently and advantageously, this same concave reflector is utilized on a return path, obviating the requirement of matching elements. In one embodiment a single focussing/collimating lens is provided substantially at a focal plane of the element having optical power.

摘要： The Holographic Beam Combiner, (HBC), is used to combine the output from many lasers into a single-aperture, diffraction-limited beam. The HBC is based on the storage of multiple holographic gratings in the same spatial location. By using a photopolymer material such as quinone-doped polymethyl methacrylate (PMMA) that uses a novel principle of nullpolymer with diffusion amplificationnull (PDA), it is possible to combine a large number (N) of diode lasers, with an output intensity and brightness 0.9 N times as much as those of the combined outputs of individual N lasers. The HBC will be a small, inexpensive to manufacture, and lightweight optical element. The basic idea of the HBC is to construct multiple holograms onto a recording material, with each hologram using a reference beam incident at a different angle, but keeping the object beam at a fixed position. When illuminated by a single read beam at an angle matching one of the reference beams, a diffracted beam is produced in the fixed direction of the object beam. When multiple read beams, matching the multiple reference beams are used simultaneously, all the beams can be made to diffract in the same direction, under certain conditions that depend on the degree of mutual coherence between the input beams.

The interferometer includes a first optical path and a second optical path. A plurality of optical phase modulators is arranged in said first path to include one optical phase modulator for each wavelength component. Each wavelength component is split into a wavelength component first portion on the first optical path and a wavelength component second portion on the second optical path. Each optical phase modulator is selectively operable to phase shift the corresponding one wavelength component first potion by first or second predetermined phase shifts, whereby the wavelength component is or is not coupled from the input port to the output port.

摘要： An integrated WDM device is provided by replacing fiber routing with a birefringent routing element, e.g. a rutile crystal. The device has a routing block for directing an incoming polarized light beam launched into its input port in one of two directions in dependence upon the polarization state of the light beam. A plurality of thin film filter (TFF) elements is provided in a zig-zag pattern on both faces of the routing block for filtering specific wavelengths of the beam. A rotator is provided for rotating the polarization of a portion of the beam so that it follows a separate path after reflection from the optical filter element, the path corresponding to the zig-zag arrangement of the TFF elements. If the incoming beam is non-polarized, polarization diversity elements are disposed in the optical path of the beam to control the polarization. The device may function as a WDM or as an add/drop multiplexer/demultiplexer.

摘要： The invention is an optical ADD/DROP filter suitable for dense wavelength division multiplexing/de-multiplexing. It comprises an optical bench having a longitudinal V-groove into which the optical components of the ADD/DROP filter are passively aligned and bonded. The bench further includes first and second pairs of opposed, spaced, vertical members at each end between which a fiber array block is inserted. In the method of constructing the ADD/DROP filter, an interference filter is bonded to a first collimating lens. Then, the first collimating lens with the interference filter attached thereto and a second collimating lens are placed in the V-groove of the bench where they are passively aligned. The two collimating lenses are then bonded to the bench. Fiber array substrates are inserted between the pairs of opposed, spaced, vertical members and a UV transparent block is inserted on top of each fiber array between the corresponding pair of opposed, spaced, vertical members. The fiber arrays are actively aligned. After proper alignment is achieved, adhesive is wicked into the spaces between the fiber array, the block and the vertical members. The adhesive is then cured.

摘要： A grating type optical component is provided, in which a plurality of light beams having wavelengths different from one another can be reflected, the, loss is small, and the cost is low. The grating type optical component is composed of plural kinds of gratings (6a to 6d) that reflect different wavelengths of light and are formed at once in an optical fiber (2) and arranged serially in its longitudinal direction, so that there are no fusion splicing portions between the gratings. The plural kinds of serially-connected gratings (6a to 6d) are together housed in a temperature compensating package (3N) for compensating the temperature dependency of the gratings (6a to 6d). In forming the gratings (6a to 6d), prepare a phase mask (8N) in which a plurality of grating forming patterns (1a to 1d) different from one another are formed and arranged transversely. The phase mask (8N) covers the optical fiber (2) such that the grating forming patterns (1a to 1d) face the optical fiber (2). The optical fiber (2) is then irradiated with ultraviolet light through the phase mask (8N).
