    Abstract: The present invention relates to a light source apparatus having a structure for stably supplying broadband pulsed light having a wavelength spectrum with an excellent flatness over a wide band. The light source apparatus employs, as a seed light source, a short-pulsed light source having such an excellent output pulse characteristic that the frequency bandwidth extending until the output pulse drops by 10 dB or 20 dB from a peak is 5 THz or more. The light source apparatus also includes a broadband light producing fiber having an optical characteristic suitable for combining with the short-pulsed light source. The broadband light producing fiber inputs pulsed light from the pulsed light source, and produces the broadband pulsed light by utilizing a nonlinear optical phenomenon. This structure yields broadband pulsed light having such a wavelength spectrum that a region whose power fluctuation is suppressed to 6 dB or less extends over 100 nm or more.

    Abstract: Th end face (7a) of an optical fiber (7) and the end face (8a) of an optical fiber (8) are disposed in a V-groove (23) in a base (21) opposite to each other and a specified distance apart. A solution (27) serving as the material of a photonic crystal and containing fine particles is dripped into a space (25) defined by the end face (7a), the end face (8a) and the V-groove (23). Accordingly, a photonic crystals are respectively grown from the end face (7a) and the end face (8a) to thereby form optical control units containing photonic crystals (2) at the end face (7a) and the end face (8a) respectively.

    Abstract: A method of thermally poling a silica based waveguide (12) comprises exposing a region of the waveguide (12) to an electric field (for example, via capillary electrodes (22, 24) inserted into holes in the waveguide); directing a laser beam (18) into the region exposed to the electric field to effect localised heating of the region via direct absorption; and scanning the laser beam (18) over the region at a rate selected to avoid heating of the region above the glass transition temperature. Reversing the electric field while scanning the laser beam (18) allows the formation of periodic poled gratings. The waveguide (12) can comprise an optical fibre.
