    摘要: An optical filter is manufactured by placing a photosensitive optical fiber in a spiral arrangement on a fiber holder, preferably having a spiral groove for holding the fiber, and exposing the fiber to ultraviolet light through a phase mask having a spiral diffraction grating, forming an in-fiber Bragg grating. The fiber can be conveniently scanned by an ultraviolet beam as the fiber holder and phase mask turn on a rotating stage. The fiber can be compactly packaged between the fiber holder and a cover. The fiber holder and cover can be formed by coating a substrate with layers of polymer material, the spiral groove being formed by photolithographic patterning of one of the layers.

    摘要: An optical signal encoder/decoder includes a grating waveguide having an identical number of uniform pitch gratings to the number of code chips of a binary phase optical code, the uniform pitch gratings being formed in a waveguide direction to reflect light of a predetermined wavelength. Here, adjacent gratings corresponding to a position at which the optical code value changes are disposed a spacing apart from each other to give a phase shift of (2m+1)π/2 to the light, and the remaining adjacent gratings are disposed a spacing apart from each other to give a phase shift of nπ to the light (m, n: integer).

The SSFBG is fixed to contact an FBG contact portion that is established on the upper face of the mounting plate. The phase modulation portions are formed to be capable of expanding and contracting and, as a result of the expansion and contraction of the phase modulation portions, the phase of the carrier wave of the optical pulse signal that is propagated by the phase modulation portions can be changed.

    摘要: An automatic document conveying device comprising a paper-feeder for sequentially separating one document sheet from a stack of document sheets loaded on a document loading table and for sequentially transporting each document sheet to a standby position upstream of an image exposure section and for halting each document sheet at the standby position, the standby position being variably determined by the length of each document sheet. A conveyor conveys each document sheet from the standby position to an exposure position on the image exposure section on a glass surface of the document loading table, each document is discharged after it is scanned and exposed by the image exposure section. The image exposure section is controlled to scan and expose a first document sheet, and a second document sheet is halted at the standby position while the first document is being scanned and exposed. The first document sheet is discharged after it has been scanned and exposed, and the second document sheet is conveyed from the standby position to the image exposure position when discharge of the first document begins. A third document sheet is then conveyed to the standby position at least before the scanning and exposure of the second document at the image exposure position is completed. The paper-feeder, conveyor and discharge device are operated until the entire stack of documents loaded on the document loading table is scanned and exposed.

    摘要: A phase control arrangement has a structure in which a Superstructured fiber Bragg Grating (SSFBG) 40 has fifteen unit Fiber Bragg Gratings (FBGs) arranged in series in a waveguide direction. The SSFBG 40 is fixed to the core of an optical fiber 36 that includes a core 34 and cladding 32. The difference Δn between the maximum and minimum of the effective refractive index of the optical fiber is 6.2×10−5. The phase difference of Bragg reflected light from two unit diffraction gratings that adjoin one another from front to back and provide equal code values is given by 2πM+(π/2), where M is an integer. Further, the phase difference of the Bragg reflected light from two unit diffraction gratings that adjoin one another from front to back and provide different code values is given by 2πM+(2N+1)π+(π/2) where M and N are integers. The ratio P/W between the peak value P and the subpeak value W of the autocorrelation waveform, and the ratio P/C between the peak value P of the autocorrelation waveform and the maximum peak value C of the cross correlation waveform are both large.
