The grating (12) having a plurality of colocated pitches Λ which represent a unique identification digital code that is detected when illuminated by incident light (24).

The element (8) can provide a large number of unique codes, e.g., greater than 67 million codes, and can withstand harsh environments. The element (8) can be used in any application that requires sorting, tagging, tracking or identification, and can be made on a micron scale "microbeads" if desired, or larger "macrobeads" for larger applications. The code may be digital binary or may be other numerical bases.

    Abstract: A multi-core optical waveguide 10, such as a dual core waveguide, having a pair of cores 12,14 disposed within a cladding 13 is provided. The cores are equally spaced and parallel to the axis of the waveguide. The cores can be spaced to provide optical coupling between the cores. The outer dimension d2 of the cladding 13 is at least about 0.3 mm; and the outer dimension d1 of the cores 12,14 is such that they propagate in a single spatial mode. The multi-core waveguide may be used in many optical components, such as a bandpass filter and an optical add/drop multiplexer. For the bandpass filter, a Bragg grating having the same reflection wavelength is written into both cores at substancially the same distance from the imput end 86,87 of the cores. The cores 12,14 have the same propagation constants to permit coupling of all the energy of the WDM input signal 84 from one core to the other. The length of the waterguide 100 is substantially equal to the coupling length (L c ), provided all the energy of the through wavelengths is desired at the output end of the second core. Generally, the grating 82 is substantially centered in the waveguide at L c /2.

    Abstract: A tunable Raman (40) laser and amplifier include a pair of tunable optical units (42, 44) optically connected by a length of optical fiber (46) having an associated Raman gain. The tunable optical units (42, 44) tune respective optical waveguides (50, 60), each of which includes an inner core (56) disposed within an outer cladding (58). A plurality of Bragg gratings (51-54, 61-64) is written in each core (56) of the waveguides (50, 60). The reflexion wavelengths of each Bragg grating (51-54) of the input waveguide (50) is the same as the reflection wavelength of a matched grating of the output waveguide (60), to thereby form a plurality of cascaded resonance cavities. Each resonance cavity has a reflecting wavelength equal to the center wavelength of successive Stokes orders associated with optical fiber. The Bragg gratings (51-54, 61-64) of each waveguide (50, 60) are written into a corresponding stepped region ground into the outer cladding (58) of the waveguides (50, 60). The tuning (e.g., compression) of the waveguides proportionally changes the reflexion wavelengths of the gratins, and thereby proportionally changes the center wavelength of each resonance cavity. This method of proportionally tuning each matched pair of Bragg gratings enables the Raman laser to be tunable over an extended wavelength range.
