The spectral and group delay characteristics are studied and the potential uses of this type of grating for wavelength selection and dispersion compensation are discussed. a novel scheme of oadm configuration based on linearly chirped moir fiber gratings is proposed. we have designed a lcmfg to compensate dispersions for eight channels at the same time

Results show that the sidegating threshold voltage is higher when adjacent devices are isolated by boron implanted, which means that boron implantation significantly improves the electronical isolation between devices and reduces the sidegating effect

We also studied some characteristics of sidagating effect using mesfet fabricated in planar boron implanted process including photosensitive, hysteresis, influence of sidegating effect on mesfet threshold voltage, influence of drain - source voltage on sidegating threshold voltage, influence of exchanging drain and source electrode on sidegating threshold voltage, relation between sidegating threshold voltage and the distance between side - gate and mesfet, relation between sidegating effect and floating gate, and so on
