    摘要: A channel switching function is added to a wavelength division multiplexing passive optical network (WDM-PON) system, which is an access optical network system, and the potential transmission rate is increased by combining wide wavelength tunable lasers and a time division multiplexing (TDM) data structure and properly using the necessary optical components. In addition, when the wavelength of a light source or an arrayed waveguide grating (AWG) changes, the wavelength is traced and the magnitude of a transmitted signal is maximized without an additional detour line using a loop-back network structure. Furthermore, fewer thermo-electric controllers (TECs) are required for stabilizing the temperature of an optical line terminal (OLT) using wavelength tunable lasers, each laser electrically changing its wavelength.

    摘要: The present invention relates to a spot size converter and a method of fabricating the same, which provides efficient coupling between an optical fiber and integrated devices of optical waveguide. The spot size converter has an input and output optical waveguides formed in a vertical double-layer structure. Integrated to the output optical waveguide, an unidirectional side-tapered optical waveguide is formed. Due to the tapered structure of the optical waveguide, the effective refective index gradually changes along the length of the waveguide. Thus, the spot size of the optical signal gradually changes while the optical signal travels within the tapered optical waveguide. Therefore, the present invention effectively eliminates or minimizes the coupling loss and the reflection loss between the optical fiber and the devices connected to the spot size converter. In particular, the present invention provides method for easily fabricating a tapered and narrow optical waveguide structure using low-resolution photolithography technique and reducing the manufacturing cost and increasing the manufacturing yield at the same time.

    摘要: Filter-free wavelength converters for separating and rejecting an optical input signal. A first input port couples a continuous wave (CW) light. A second input port couples an optical input signal. A multimode interference semiconductor optical amplifier (MMI-SOA) determines the output port with the input port and intensity-modulation of the CW light with the optical input signal. A first output port guides the converted signal, and a second output port guides the optical input signal.

    摘要: Provided is an optical deflector for deflecting radiation beams. The optical deflector includes: a peripheral region having a first effective refractive index; and a deflection pattern region having a predetermined shape and a second effective refractive index, wherein the second effective refractive index differs from the first effective refractive index. Here, due to the deflection pattern region having the predetermined shape, the radiation beams are deflected in a direction starting from a certain point. By using the optical deflector, the locus of a light source can be designed in one of various forms, such as a straight line, a circle, an ellipse, or a parabola.
