摘要： A dynamic power equalizer comprises an array waveguide grating having an input waveguide and an output waveguide at one end, and an input waveguide group and an output waveguide group at the other end. The double loops are composed of the input waveguide and the output waveguide group, and the input waveguide group and the output waveguide are used to process the input optical signal components having different powers into the output optical signal having a single and equalized optical power through wavelength-division de-multiplexing and wavelength-division multiplexing, thus achieving dynamic optical power equalization.

摘要： A thermo-optic wave-guide switch. The switch selectively switches the paths of an optical signal. The thermo-optic wave-guide switch includes a multi-mode wave-guide having an input port, a first output port and a second output port, and a thin film heater formed on the side of the multi-mode wave-guide. When the thin film heater does not provide the multi-mode wave-guide with heat and a signal is received by the input port, the first output port outputs the signal in a cross state according to the self-image theorem, and when the thin film heater provides the multi-mode wave-guide with heat and a signal is received by the input port, the second output port outputs the signal in a bar state.

摘要： Along with several few-channel and low-density wavelength division multiplexer/de-multiplexer, a novel planar lightwave circuit (PLC) interleaver is invented to achieve high-density wavelength division multiplexing and de-multiplexing in a wavelength division multiplexing fiber communication system. The invention uses a PLC as its basic structure and applies the principle that the product of the number of output optical waveguides and the channel spacing is equal to the free spectral range of the spectrum of any output optical waveguide to make a compact PLC interleaver.

摘要： A partial reflective laser output device comprising a partial reflective unit mounted on a laser output device (such as a vertical cavity emitting laser), the partial reflective unit allowing the laser beam emitted from the laser output device to be partially reflected while the rest penetrating through. On one hand, this device decreases the intensity of output laser light so as to comply with the eye safety standard; the reflected light is absorbed by a photodiode (PD) to perform auto power control on the laser output device on the other. In addition, by adjusting the tilting angle of the partial reflective unit or making a curvature thereon, the reflected light can have no destructive interference with the output light and can even be focused onto the PD so that there would be no relative intensity noise problem and the size of the PD can be made smaller to lower the cost.

摘要： A reflectivity-tunable fiber reflector is disclosed. The Bragg reflectivity of the fiber grating is modulated by exciting the transverse vibration of the fiber through an acoustic wave. The excitation of the transverse vibration, leading to fiber grating tilting and fiber micro-bending, induces the coupling of the fiber core mode into cladding modes. This leads to the reduction of core-mode power and hence that of Bragg reflection. This mechanism is applied by this invention to control the reflectivity of a fiber optic Bragg grating after fabrication. The fiber reflector is suitable for fiber-compatible acousto-optical switching.
摘要翻译：公开了一种反射率可调光纤反射器。光纤光栅的布拉格反射率通过声波激发光纤的横向振动来调制。横向振动的激发导致光纤光栅倾斜和光纤微弯曲，引起光纤纤芯模式耦合到包层模式。这导致核心模式功率的降低，从而导致布拉格反射的降低。本发明应用该机制来控制制造后的光纤布拉格光栅的反射率。光纤反射器适用于光纤兼容的声光切换。
