引入切趾啁啾光纤光栅的SOA光缓存器 研究

Optical buffer which is based on semiconductor optical amplifier(SOA) as signal reading switch is called SOA optical buffer. As storing time increasing, signal quality in SOA optical buffer is constantly reduced. The main research point is to use apodized and chirped fiber grating(ACFG) for optimizing the quality of optical signal. Under the conditions of optical buffer with and without ACFG, using Opti-system 7.0 software to simulate the system and comparatively analyse the parameters of optical pulse. Synthetically consider the factors including the compressing ratio of optical pulse, energy loss ratio and optical signal noise ratio(OSNR), all of which are used to measure the quality of optical pulse. Discuss how ACFG influences the storing time and improves the quality of optical pulse in optical buffer.
