    Abstract: An embodiment of a waveguide has a Brillouin bandwidth, and includes cladding and a core. The cladding includes first layers of a first material, each first layer having a physical characteristic of approximately a first value, and includes second layers of a second material, each second layer having the physical characteristic of approximately a second value, the second layers alternating with the first layers such that the Brillouin bandwidth is wider than the Brillouin bandwidth would be if the cladding excluded the first layers or excluded the second layers. For example, the first and second cladding layers can be formed from different materials, or can be formed having different values of a physical characteristic such as thickness, acoustic velocity, or index of refraction. Such a waveguide can facilitate alignment of the waveguide's optical bandwidth with the waveguide's Brillouin bandwidth because the Brillouin bandwidth is widened compared to conventional waveguides.

    Abstract: A method for preparing an article includes applying a first composition on a substrate to form a first layer, and applying a curing condition to a target portion without applying the curing condition to a non-target portion of the first layer to form a first contrast layer. A second composition is then applied on the first contrast layer to form a second layer, and a curing condition is applied to a target portion without applying the curing condition to a non-target portion of the second layer and first contrast layer to form a second contrast layer. A third composition can optionally be applied and cured on the second contrast layer to form a third contrast layer having a cured and uncured portion in the same manner. The uncured portions of these contrast layers are then selectively removed to prepare the article.

    Abstract: A method and an apparatus for coupling an optical waveguide to a single-mode fiber are disclosed. The method includes: forming a locating slot (23) on a substrate (21), where a first optical waveguide (22) is further disposed on the substrate (21), one end of the first optical waveguide has an inverted taper structure (22a) whose width is gradually decreased, and a taper tip of the inverted taper structure (22a) is parallel to a center line of the locating slot (23); horizontally fastening, into the locating slot (23), a single-mode fiber (24) with one end having an optical fiber taper structure (24a) whose diameter is gradually decreased, so that the end, having the optical fiber taper structure (24a), of the single-mode fiber (24) is extended outside the locating slot (23) along a direction of the first optical waveguide; and disposing a second optical waveguide (25) on the substrate according to a location of the first optical waveguide (22) and a location of the single-mode fiber (24), so that the second optical waveguide (25) is coupled to the first optical waveguide (22) and the single-mode fiber (24). The provided method for coupling an optical waveguide to a single-mode fiber can lower an alignment precision requirement on a coupling device and reduce production costs.
