We analyse the temporal properties of the optical pulse wave that is obtained by applying a discrete set of spectral π/2 phase shifts to continuous-wave light that is phase-modulated by a temporal sinusoidal wave. We develop an analytical model to describe this new optical waveform that we name ‘besselon’. We also discuss the reduction of sidelobes in the pulse intensity profiles by means of an additional spectral π phase shift, and show that the resulting pulses can be efficiently time-interleaved. The various predicted properties of the besselon are confirmed by experiments demonstrating the generation of low duty cycle, high-quality pulses at repetition rates up to 28 GHz.

我们分析了通过将离散的一组光谱π / 2相移应用于由时间正弦波进行相位调制的连续波光而获得的光脉冲波的时间特性。我们开发了一个分析模型来描述这种称为“ besselon”的新光波形。我们还讨论了通过额外的频谱π相移来减少脉冲强度曲线中的旁瓣，并表明可以有效地对所产生的脉冲进行时间交织。可以通过实验证明贝塞尔龙的各种预测特性，这些实验表明在高达28 GHz的重复频率下会产生低占空比，高质量的脉冲。
