Item type:Item, CONCATENATED SOLITON FIBER LINK(1991-01-31) ;CHI, S ;LIN, MC ;光電工程學系 ;電信研究中心Department of PhotonicsAn easy and practical 'soliton fibre' link by concatenating uniform fibre sections is proposed. An ultrahigh bit rate loss-limited fibre communication system can be achieved.Item type:Item, ELECTRICAL-PROPERTIES OF AMORPHOUS BARIUM-TITANATE FILMS PREPARED BY LOW-POWER RF-SPUTTERING(1994-08-15) ;CHIOU, BS ;LIN, MC ;電子工程學系及電子研究所Department of Electronics Engineering and Institute of ElectronicsIn this study r.f. magnetron sputtering is employed to deposit amorphous Ca-doped titanate film on silicon substrate. The as-deposited BaTiO3 film has a 1 MHz dielectric constant of 14 and a refractive index of 1.9 at a wavelength of 6328 angstrom. The capacitance voltage characteristics of the BaTiO3 film suggest a Poole Frenkel transport mechanism with oxygen vacancies as one of the positively charged traps. The remanent polarization in the BaTiO3 films affects its current voltage curve. The fatigue behaviour of the BaTiO3 films is improved by the introduction of oxygen gas during sputtering and/or the addition of dopant calcium. No fatigue is observed for (Ba0.9Ca0.1)TiO3 film up to a switching cycle of 10(10).Item type:Item, INFORMATION RATE OF MCELIECE PUBLIC-KEY CRYPTOSYSTEM(1990-01-04) ;LIN, MC ;CHANG, TC ;FU, HL ;應用數學系Department of Applied MathematicsItem type:Item, OPTIMAL TRANSMISSION CONDITION OF NONLINEAR-OPTICAL PULSES IN SINGLE-MODE FIBERS(1993-04-01) ;LIN, MC ;CHI, SE ;光電工程學系Department of PhotonicsOptimal transmission conditions of nonlinear optical pulses in single-mode fibers are presented. When an optical pulse propagates in a fiber, it suffers the fiber loss, group velocity dispersion, and self-phase modulation. An optimal output pulse can be obtained by choosing a suitable optical carrier wavelength and an initial input pulse. The system at the optimal condition not only has more stable performance than the dispersion-free system, but also achieves maximum transmission bitrate for a fixed transmission distance. The bit-length product up to 8550 Gb/s.km or more can be achieved by using dispersion-shifted fibers without amplification.Item type:Item, OPTIMUM TRANSMISSION CONDITIONS OF SOLITONS BY PREEMPHASIS TECHNIQUE(1990-08-30) ;CHI, S ;LIN, MC ;光電工程學系 ;電信研究中心Department of PhotonicsItem type:Item, THE GAIN AND OPTIMAL LENGTH IN THE ERBIUM-DOPED FIBER AMPLIFIERS WITH 1480 NM PUMPING(1992-04-01) ;LIN, MC ;CHI, S ;光電工程學系 ;電信研究中心Department of PhotonicsThe approximate analytic expressions for the gain and optimal length of the 1480 nm-pumped erbium-doped fiber amplifier with an arbitrary dopant distribution are obtained when the saturation by ASE is neglected. Numerical calculations show that the values predicted from the analytic expressions of the maximal gain and optimal fiber length as functions of input signal and pump powers are very accurate for narrow dopant distributions confined to the center of the fiber core.
