A Bloch surface wave (BSW)-based coherent light source and associated waveguide are proposed as an on-chip sensing scheme making use of BSW high confinement near the structure/air interface as well as BSW small propagation losses. We have designed and fabricated the on-chip optical sensor comprising integrated coherent light sources and bus waveguides on a dielectric multilayer and obtained guided BSW modes. So far, lasing has been achieved with a 0.2 nm bandwidth, and the propagation length of the guiding mode was 80 microns. The sensing ability of the device based on the change in the effective index of the lasing mode in the presence of analytes produces a wavelength shift of 0.17 nm. The scheme requires further optimization to realize on-chip high-throughput optical sensors.

利用布洛赫表面波在结构/空气界面附近的高约束和布洛赫表面波的小传播损耗，提出了一种基于布洛赫表面波的相干光源和相关波导的片上传感方案。我们设计并制作了在介质多层上集成相干光源和总线波导的片上光学传感器，并获得了波导BSW模式。到目前为止，激光已经实现了0.2 nm的带宽，引导模式的传播长度为80微米。在分析物存在的情况下，该器件基于激光模式有效指数变化的传感能力产生0.17 nm的波长位移。该方案需要进一步优化才能实现片上高通量光传感器。
