脉冲无线超宽带（IR-UWB）是超宽带技术（UWB）最经典的实现方式之一，产生脉冲宽度在亚纳秒级别，能利用具有低占空比的基带窄脉冲序列来携带信号。IR-UWB的发生器可以灵活的产生脉冲信号，并且具有体积小、质量轻、噪声小、可调性高和抗电磁干扰等优势。文中具体研究了五种IR-UWB脉冲信号的光学生成方法，分别是利用光脉冲压缩产生IR-UWB脉冲信号、基于相位调制和偏振分束器IR-UWB脉冲信号、基于相位调制和切趾光纤光栅产生IR-UWB脉冲信号、利用光学带通滤波器产生IR-UWB脉冲信号以及基于半导体激光器产生IR-UWB脉冲信号。通过对比国内外在本领域的研究成果，讨论和总结了以上几种IR-UWB的光学生成方法，并比较各种实现方法的优缺点。

Impulse radio ultra-wide band (IR-UWB) is one of the most classical ultra-wide band (UWB) imple?mentation schemes. The generated pulse width is at sub-nanosecond level, which can take advantage of baseband narrow pulse sequence with low duty ratio to carry signals. And the IR-UWB generator with the advantages of small volume, light weight, low noise, good tunability and anti-electromagnetic interference may generate pulse signals flexibly. Five IR-UWB pulse signal optical generation methods such as IR-UWB pulse signal generated by optical pulse compression, IR-UWB pulse signal based on phase modulation and polarized beam splitting system (BPS), IR-UWB pulse signal based on phase modulation and generated by apodized fiber Bragg grating (AFBG), IR-UWB pulse signal generated by optical band-pass filter and IR-UWB pulse signal generated by semiconductor laser are re?searched. By contrasting research results in China and foreign countries in this field, IR-UWB optical generation methods hereinbefore are discussed and summarized and the advantages and disadvantages of the methods are com?pared.
