Abstract: The present invention provides a novel poly(1,3-propylene terephthalate), which is prepared from reacting terephthalic acid and 1,3-propanediol in the presence of an effective catalytic amount of ethylene glycol titanate to undergo esterification to form a monomer; and polymerizing the monomer in the presence of an effective catalytic amount of antimony acetate to obtain poly(1,3-propylene terephthalate). The obtained poly(1,3-propylene terephthalate) (PPT) has an intrinsic viscosity (IV) of 0.65-0.91 dl/g, acid number (--COOH amount) of less than 40 meq/kg, and L*>60. Without adding a pigment, the yellowness b* of PPT is below 9, even below 5. The yellowness b* of PPT even reaches below 3 when a pigment is incorporated.

Abstract: A tunable optical fiber filter or reflector is composed of a single-mode optical fiber having UV-induced fiber gratings in its core region. A planar surface is formed by a mechanical polishing technique such that the planar surface is contiguous to the core region of the optical fiber. The planar surface is covered with a material having a refractive index close to the refractive index of the optical fiber. As the refractive index of the material is changed, the tuning of the reflection or transmission spectra of the optical fiber filter or reflector is attained. The tunable optical fiber filter or reflector is used in optical communication systems, sensoring systems, or as external cavities of lasers.

Abstract: A method for preparing a fiber-optic polarizer involves a first step in which the cladding layer of a single-mode optical fiber is side-polished to form a planar surface contiguous to the core region of the single-mode optical fiber. The planar surface is formed thereon a buffer dielectric/metal composite thin film, or the planar surface is coated by sputtering with a metal layer which is then coated with a medium having a refractive index matching to that of the optical fiber. The polishing of the single-mode optical fiber is done by using a semiconductor substrate having one or more V-shaped recesses having a large curvature radius.

Abstract: The present invention is related to a flexible IC layout method utilized for an IC having a plurality of logic gates in a first direction connected with a plurality of logic gates in a second direction wherein each of the logic gates has at least one polysilicon region and each of the logic gates in the first direction has an output serving as an input of a corresponding one of the logic gates in the second direction, which includes a step of forming input terminals for the logic gates by ion implantation. The present invention is flexible because the addition or deduction of the number of the input terminals according to the present invention can be achieved by ion implantation.
