我们通过微操纵硫氰酸染料纳米纤维沿光纤传播激子极化子，制作了微米级环形谐振器沟道降滤光器。该器件由半径为r≈4µm的微环和作为I/O总线通道的直纳米光纤组成。使用空间分辨荧光显微镜对该装置的性能进行了评估。该器件在490-540 nm的可见光波长范围内的消光比为Re=2-4d B。我们的结果表明，硫氰酸纳米纤维是激子偏振子光子电路的很有前途的构建块，与传统的基于波导的光子电路相比，这种光子电路可以高度小型化。
We fabricated a micron-sized ring resonator channel drop filter by micromanipulation of nanofibers of thiacyanine dye that propagate exciton polaritons along the fibers. The device consisted of a microring with a radius of r≈ 4 µm and a straight nanofiber that functioned as an I/O bus channel. The performance of the device was evaluated using spatially resolved fluorescence microscopy. The device exhibited an extinction ratio of re= 2–4 dB for the visible wavelength region of 490–540 nm. Our results demonstrate that thiacyanine nanofibers are promising building blocks for exciton polariton-based photonic circuits, which can be highly miniaturized compared with conventional waveguide-based photonic circuits.
