摘要： There is provided a millimeter wave band frequency optical oscillator predicted to be used as a millimeter wave oscillating frequency signal source in a base station of a millimeter wave wireless transmission system. The optical oscillator has a double resonator structure in which a pair of wavelength tunable fiber grating mirrors are inserted into a unilateral fiber-ring laser resonator in order to internally and additionally form a linear laser resonator. The double resonator structure composed of the two stable laser resonators can oscillate laser of two modes. Due to a beat phenomenon occurring between the two modes, received laser is modulated to an ultra-speed frequency of 60 GHz or greater. A variation in the gain within a resonator is induced by a polarization controller using the dependency of laser modes upon polarization. A modulation frequency is consecutively changed from 60 GHz to 80 GHz by controlling the wavelength of light reflected by the fiber grating mirrors.

摘要： The present invention relates to a field emission display which applies a field emission device (or field emitter) to a flat panel display. The field emission display in accordance with the present invention has the lower plate in which the pixel array and the scan and data driving circuits are integrated one insulating substrate, therefore, it is possible to implement a field emission display capable of providing a high quality picture in a low price. The voltage is applied to the scan and data driving circuits may considerably decrease through the tin film transistor attached to each pixel. The field emission characteristics are stabilized by the resistor attached to the field emission device so that reliable field emission display may be fabricated. Further, since all the processes are carried out at a low temperature, a glass, which is low in price and has a large area, may be used as an insulating substrate.

摘要： A microstrip cross coupling bandpass filter includes an input port, an input resonator, an output port, and an output resonator. The input port and the input resonator are electric-coupled, and the output port and the output resonator are electric-coupled. A cross coupling gap corresponding to the distance between the input and output resonators forms magnetic coupling. The bandpass filter further includes a cross coupling line electric-coupled with the input and output ports. The cross coupling gap generates an attenuation pole on the high side of a passband. The attenuation frequency of the attenuation pole can be varied with the distance of the cross coupling gap. The cross coupling line generates an attenuation pole on the high and low sides of the passband.
