    摘要: Provided is a wavelength division multiplexer/demultiplexer having a flat wavelength response. In the wavelength division multiplexer/demultiplexer, a modified taper-shaped optical waveguide is interposed between an input waveguide and a first slab waveguide, such that the distribution of an optical signal input to an Arrayed Waveguide Grating (AWG) has a sinc-function shape. Thus, a flat wavelength response can be obtained in an output waveguide. In addition, the modified taper-shaped optical waveguide interposed to obtain a flat wavelength response has a small size and a simple structure, and thus can be applied to a conventional wavelength division multiplexer/demultiplexer without a design change.

    摘要: Provided is a wavelength selective switch (WSS), and more particularly, a wavelength selective switch for electrically switching a wavelength without physical displacement. The wavelength selective switch includes an optical demultiplexer for dividing an input optical signal into signals having wavelengths corresponding to respective channels, selecting either the optical signal of each channel obtained by dividing the input optical signal or an optical signal input via an add port, and outputting the selected optical signal; and an optical multiplexer including an optical deflecting unit for individually deflecting the optical signals of the respective channels received from the optical demultiplexer according to supplied current or applied voltage, wherein the optical signal of each channel deflected by the optical deflecting unit is output to a specific output port. In the wavelength selective switch, current is supplied to the optical deflectors to switch the channels, resulting in higher reliability, smaller volume and higher switching speed than a conventional wavelength selective switch using mechanical displacement to switch channels.
