Omni-resonant wave packets are pulsed optical beams that couple to planar cavities even when the wave packet bandwidth far exceeds the cavity resonant linewidth by virtue of a precise spatiotemporal structure introduced into the optical field. We demonstrate experimentally the synthesis of programmable omni-resonant wave packets in which a prescribed pulse spectrum is made to resonate with a planar cavity. Examples include controllable-bandwidth resonant spectral lines, spectral holes with tunable notch bandwidth, and even arbitrary resonant spectra. These novel resonant interactions are realized with no changes made to the cavity itself, and therefore, without compromising its quality factor—only sculpting the spatiotemporal spectrum of the incident field is required. Programmable omni-resonance allows harnessing resonant field enhancements over arbitrary spectral profiles without restriction to traditionally narrow resonant linewidths.

使用时空场的可编程全共振

全谐振波包是脉冲光束，即使由于波包带宽由于引入光场中的精确时空结构而远远超过腔谐振线宽时，它们也耦合到平面腔。我们通过实验证明了可编程的综合全向波包，其中使规定的脉冲频谱与平面腔谐振。示例包括可控制带宽的共振谱线，具有可调陷波带宽的光谱孔，甚至是任意共振谱。这些新颖的共振相互作用是在不对腔体本身进行任何更改的情况下实现的，因此，在不影响腔体品质因数的情况下，只需对入射场的时空光谱进行雕刻即可。可编程全共振允许在任意频谱轮廓上利用共振场增强，而不受限于传统上较窄的共振线宽。
