纳秒工艺研究机构研究的兆兆比特大容量光通信网络需要的全光开关大规模集成电路芯片。现已经证明低功率,200 fs以下的最高速度。利用偏振光控制的这种光开关,即使用缓慢的非线性光学材料,也能使偏光产生相移,以低功率获得超高速动作。用气相生长方法,使石英波导和光纤固定用V型槽形成一体,在波导的中部用InGaAsP块来做 Nanosecond Process Research Institute of the trillion-bit high-capacity optical communications network required all-optical switching LSI chips. Now it has been proven that low power, 200 fs maximum speed below. The use of polarization control of this optical switch, even with a slow non-linear optical materials, but also polarization can produce a phase shift, low power ultra-high speed operation. Using the vapor phase growth method, the quartz waveguide and the V-groove for fixing the optical fiber are integrated, and the InGaAsP block is used in the middle of the waveguide
