1.概要 日本住友Cement公司,利用光集成技术生产出作为下一代光通信系统的关键性光器件—10Gbps光强度调制器和光相位调制器。由于将该公司生产的小型集成式起偏器(小型球面反射镜)装入这些调制器,所以不需要作为外部装置的输入偏振光控制器,并具有插入损耗小,低电压驱动等许多优点,它是一种很容易使用的器件。 1. Outline Sumitomo Cement Co., Ltd., Japan, uses optical integration technology to produce the 10 Gbps optical intensity modulator and optical phase modulator as the key optical devices of the next generation optical communication system. Since the company’s small integrated polarizers (small spherical mirrors) are incorporated into these modulators, there is no need for an input polarization controller as an external device, and there are many advantages such as low insertion loss, low voltage drive and the like, It is a very easy to use device.
