A method for prepring a porous aerogel scaffold includes: adding a photoinitiator and polyethylene glycol diacrylate in a buffer solution, dissolving by heating and evenly mixing, adding Pluronic® F127 (Poloxamer 407) into the mixed solution, and standing at a low temperature to obtain an aerogel scaffold material; printing a hydrogel scaffold by using a 3D printing technology, and performing UV irradiation so that a cross-linking of the hydrogel scaffold is caused to form a three-dimensional scaffold with a stable structure, performing low-temperature soaking to remove Pluronic® F127 (Poloxamer 407), and then freeze drying the three-dimensional scaffold to obtain the porous aerogel scaffold. Wherein, Pluronic® F127 (Poloxamer 407) serves as a sacrificial material which is removed after the 3D printing of the hydrogel scaffold is completed, and then a porous structure can be formed in the scaffold in combination with a freeze drying technology, which facilitates the survival, growth and proliferation of cells during the three-dimensional culture.

A polarization-maintaining dispersion-compensation microstructure fiber includes an inner core, an air-hole array in areaand an air-hole array in area. The air holes in the areaand 2 air-hole arrays are arranged in square lattice. The air-hole arrays in areasandare dislocated by half-layer along y-direction. In area, 2 air holes in the middle row are omitted to form a solid area as the inner core. 2 outer cores are located in 2 sub-areas of area, and each outer core contains 2 air holes. The long (or short) axes of the inner and outer cores are perpendicular, and the center points of the inner core and the two outer cores are located on the x-axis.

A single-core polarization-maintaining dispersion compensation micro-structured optical fiber comprises a fiber core, a first layer of air holes surrounding the fiber core, the cladding defects on the x-axis, the cladding defects on the y-axis, and the cladding. The air holes in the fiber cross section are arranged in the equilateral triangle lattice. Three consecutive air holes are omitted to form a solid area. This solid area is the fiber core. There are two cladding defects along the x-axis. Their centers are respectively located at the two vertices of the hexagon on the x-axis, which is formed by the fourth air hole ring from the core exclusive the central air hole. Each cladding defect along the x-axis contains 7 air holes and goes through from the core by only 1 layer of air holes. There are also two cladding defects along the y-axis.
