Abstract: A shape-memory polymer foam is disclosed, which is formed by kneading a shape-memory copolyester with a polymeric material having a relatively lower crystallinity in a weight ratio of 15:85 to 85:15 and then conducting a foaming process. The shape-memory copolyester is a random copolymer formed from a dicarboxylic acid mixture and a diol in excess through esterfication and polycondensation. The dicarboxylic acid mixture includes 30-99 mol % of an aromatic dicarboxylic acid and 70-1 mol % of a straight aliphatic dicarboxylic acid of C4-C10. The diol includes a straight aliphatic diol of C2-C10.

Abstract: A fiber-optic tunable filter and an intensity modulator respectively includes: a fiber having a polished surface and an evanescent-field; and a photonic crystal having plural cavities and a filler filled therein and attached to the polished surface, wherein the plural cavities and the filler decide a photonic band-gap of the photonic crystal and the photonic band-gap is adjusted to reflect a light with a specific wavelength through the evanescent interaction with the photonic crystal material. Based on the fiber side-polishing technique, all kinds of fiber active and passive devices are able to be manufactured easily, especially for a high speed intensity modulator using an EO (Electro-Optic) polymer as the filler.
