A fiber reinforced plastic article is disclosed which include a liner, at least one single material fiber layer wound on the liner, and at least one composite fiber layer wound on the single material fiber layer. The two or more microring optical resonators are arranged in any two of layers higher than, level with, and lower than a plane where the one light guide main line is disposed, andor the two or more microring optical resonators are arranged on both sides of the one light guide main line in a light guide direction. The control component may be used to determine the state of an optical switch in either a packet-switched network or circuit-switched network. Alternatively, the actuator may include a shape memory alloy which, upon transformation between states, deforms the reservoir and forces the shaving aid from the reservoir through the ejection port. The first part partly covers the first patterned layer and the common electrode line.
