The present invention provides a wideband wavelength converter with four-wave-mixing, which includes a modulated laser diode, a modulator, a first and second polarized controller, a first, second and third tunable lasers, a optical coupler, a soa wavelength converter and a multiplexer 本发明系提出一种宽频四波混合波长转换装置,其包含调变雷射光源、光调变器、第一及第二极化控制器、第一、第二及第三可调式雷射、光耦合器、半导体光放大器、及一多工器。
At present, signal pulses produced by directly modulated laser diodes have been used in optical fiber communication systems . the experiment reveals that the optical pulses from directly modulated laser diodes are far from gaussian and have near-rectangular temporal profiles with much sharper leading and trailing edges, and then a super-gaussian model, which assumes that an incident optical pulse has a super-gaussian profile, may be more suitable 但在实际的光通信系统中,人们常采用由直接调制半导体激光器产生的光脉冲作为信号脉冲,而实验结果表明这种脉冲具有比高斯脉冲更为陡峭的前沿和后沿,其脉冲形状更接近于超高斯分布,并且通常还带有一定量的啁啾。
