    • An organic-inorganic hybrid nanocomposite thin film for a high-powered and/or broadband photonic device having an organic ligand-coordinated semiconductor quantum dot layer, a photonic device having the same, and a method of fabricating the same are provided. The organic-inorganic hybrid nanocomposite thin film is composed of a stack structure comprising a polymer layer and an organic ligand-coordinated semiconductor quantum dot layer self-assembled on the polymer layer, or composed of a first composite thin film comprising a first polymer layer pattern having a first hole, and an organic ligand-coordinated first semiconductor quantum dot layer pattern filling the first hole. The organic-inorganic hybrid nanocomposite thin film may be formed by spin-coating a semiconductor quantum dot solution and a polymer solution alternately to be stacked by one layer so as to form a multi-layered organic thin film composed of a plurality of layers. The hybrid nanocomposite thin film for a photonic device may be provided by physically coupling a high concentration and broadband semiconductor quantum dot layer and a polymer layer so as to realize a photonic device with high power, broadband, high brightness, and high sensibility, and a flexible photonic device may be also provided.

    • An optical switch having reduced processing errors in a coupling region, according to the claimed invention includes an input portion having a pair of optical waveguides; an output portion having a pair of optical waveguides; a light phase shifting portion for inducing an additional phase change on light travelling in the input portion; a first light coupling waveguide for coupling between two light signals of the input portion and for providing a coupled signal with the light phase shifting portion; and a second light coupling waveguide for coupled between two light signals of the light phase shifting means and for providing a coupled signal with the output portion. The light coupling unit includes a waveguide. The switch reduces considerably any error that stems from manufacturing variations between waveguides in a coupling region since the waveguides share the error produced in a coupling region. The length of the switching element can be reduced since the coupled between waveguides is not indirect as in DC switches and BB switches. Due to the reduction in length, the output loss is reduced considerable.
    • 根据要求保护的发明,在耦合区域中具有减小的处理误差的光开关包括具有一对光波导的输入部分; 具有一对光波导的输出部; 光相移部分,用于在输入部分中行进的光线上引起附加的相位变化; 第一光耦合波导,用于耦合所述输入部分的两个光信号,并用于与所述光相移部分提供耦合信号; 以及第二光耦合波导,用于耦合在所述光相移装置的两个光信号之间,并用于与所述输出部分提供耦合信号。 光耦合单元包括波导。 由于波导共享在耦合区域中产生的误差,所以该开关显着地减少了由耦合区域中的波导之间的制造变化引起的任何误差。 开关元件的长度可以减小,因为在DC开关和BB开关中,波导之间的耦合不是间接的。 由于长度的减小,输出损耗相当可观。
