提出了一种新的用于光流控芯片的波导设计。它通过将基模耦合分别增加到82%和95%来减轻固体和液芯波导中的多模行为。此外，我们证明了一个六倍的改善，在横向限制的光引导介电微粒和荧光粒子的检测效率的两倍。
A new waveguide design for an optofluidic chip is presented. It mitigates multi-mode behavior in solid and liquid-core waveguides by increasing fundamental mode coupling to 82% and 95%, respectively. Additionally, we demonstrate a six-fold improvement in lateral confinement of optically guided dielectric microparticles and double the detection efficiency of fluorescent particles.
