Problems solved by technology

[0008] In the silicon-based time-delay adjustable optical delay line, at present, the adjustment of the delay is mainly achieved by controlling the optical phase by adjusting the refractive index of the material. Due to the characteristics of the silicon-based material itself, the adjustment efficiency is low.
