摘要： A high-performance quadratic nonlinear optical element which can exhibit a large nonlinear optical effect. The element contains a part which comprises a non-centrosymmetric monoclinic crystal, belonging to the space group Cc and the point group #9, of 4'-nitrobenzylidene-3-alkanoylamino-4-methoxyaniline of formula (I) or derivatives thereof wherein at least part of the hydrogen atoms are deuterated, and which is provided with at least one substantially optically flat surface which admits or transmits rays of light having a large electric oscillation vector component in the direction of the axis of maximum absorption present in the ac face of a nuclear crystal. In formula (I) R represents a C1 or C2 alkyl or haloalkyl.

摘要： A wide band optical fiber having a suitable wide band for communication, hardly breaking and cracking even when a press-fit type connector is connected by a sufficient pressing force having a small loss due to the press-fit connection and a high alignment accuracy, capable of minimizing a connecting loss and being connected easily to an ordinary quartz GI type optical fiber of 125 mu m diameter, and having a high interchangeability with an ordinary quartz GI type optical fiber. The wide band optical fiber is a refractive index distribution type optical fiber comprising a core of quartz glass having a refractive index distribution, a clad of quartz glass provided closely on the core, and a polymer covering layer provided closely on the clad, and characterized in that the polymer covering layer is made of an ultraviolet ray-cured hard polymer having a Shore hardness of above D55 and a thickness of above 5 mu m. Primary and secondary covering layers are provided closely on this optical fiber to obtain an optical fiber core wire. A polymer sheath layer is provided on the optical fiber core wire to obtain an optical fiber cord.
