Ahmet Soysal, Suad sedki, Alexander Pavlov

摘要:

我们证明了啁啾布拉格光栅可以通过在光栅轴的不同位置反射不同的波长来补偿色散。在本文中,我们利用这样的色散补偿属性,以创建一个白光腔(WLC)的效果,取消由于传播的光频率调谐的往返相移。一对LCBG用于制作腔。为了满足WLC条件,LCBG的色散分布是通过调整参数,如啁啾率,调制深度和光栅区域的长度定制。数值模拟结果表明,WLC的带宽约为10GHz。

英文摘要:

We have demonstrated that chirped Bragg gratings can compensate for a chromatic dispersion by reflecting different wavelengths at different location along the axis of the gratings. In this paper, we make use of such a dispersion-compensating property to create a white light cavity (WLC) effect that cancels the round trip phase shift due to propagation as the optical frequency is tuned. A pair of LCBGs is used to make the cavity. To fulfill WLC condition, the dispersion profile of the LCBGs is tailored by adjusting parameters such as chirping rate, modulation depth and the length of the grating region. Numerical simulation shows WLC bandwidth is ~10GHz.
