Silicon photonic switches received much attention because of their compatibility with the complementary metal-oxide-semiconductor (CMOS) process and are anticipated to be potential candidates to replace electrical switches in many applications such as data center and telecommunication. Silicon photonic switches received much attention because of their compatibility with the complementary metal-oxide-semiconductor (CMOS) process and are anticipated to be potential candidates to replace electrical switches in many applications such as data center and telecommunication. The optical circuit switch presented here is an integrated, non-blocking, switch built on a scalable silicon photonics platform. The switching mechanism is based on vertically movable adiabatic coupler waveguides controlled by micro-electromechanical-system actuators, enabling sub-microsecond. Traditional switching requires optical/electrical/optical conversions, which brings additional power consumption and requires the deployment of large amounts of cooling equipment. This increases the cost and complexity of the system. Moreover, limited by the electronic bottleneck, electrical. Recently, silicon-integrated optical circuits have attracted intensive interests, thanks to the compatibility with the complementary metal-oxide-semiconductor (CMOS) technology that enables mass production at low cost. The optical switch is an essential part of optical integrated circuits, with.
