Abstract: A folding pet staircase consists of frames and treads, wherein, the frame comprises a starting edge, a tread edge and side edges, two sides of the starting edge are connected with the side edges, two sides of the tread edge are connected with the side edges, a tread beam is arranged between the starting edge and the tread edge, baffle fixing plates are embedded in the starting edge, the tread edge and the side edges, and the tread is placed on the tread beam. The fixing plates are fixed to the specific positions by the flexible fabric frames. When the user wants to fold the pet staircase, he/she can fold the pet staircase directly along the crease lines of the fixing plates into a flat sheet structure, thus facilitating storage. The pet staircase can be used for the storage of small pet products such as toys, comb, snacks, etc.

Abstract: A demountable pet staircase is formed by installing a step plate unit, a support plate unit and a cover, wherein the step plate unit comprises a starting baffle, treads, tread baffle, a roof and a back plate, the support plate unit is composed of side support plates and a bottom support plate, and the side support plate is connected with the bottom support plate as a whole. The assembler directly forms the structure of each unit by folding along the creases on the step plate unit and the support plate unit, splices through hook and loop fasteners and fixes the cover, so that the platelike pet stairs can be spliced into a pet staircase that can be directly used by pets. The demountable pet staircase is easily assembled and disassembled, and the platelike structures formed after disassembly are convenient to carry.

Abstract: An integrated optical device and a method of fabricating the integrated optical device comprising at least one waveguide structure is provided. The waveguide structure is fabricated from a dielectric material selected from either (a) a dielectric matrix having quantum dots dispersed therein or (b) an electro-optical polymer. The fabrication method of the present invention incorporates the technique of nano-imprinting (or nano-embossing) a film of dielectric material to define the shape of the waveguide structure. The integrated optical device is operable as one of the following: a wavelength converter, a modulator, a switch, a router, a wavelength filter and a dispersion compensator.
