Self-Holding Optical Switch Using Optical Matrix Board (Special Issue on Recent Electromechanical Devices)

概要

論文の詳細を見る
A new self-holding optical switch that consists of an optical matrix board and a precision robot is proposed. Fabrication and evaluation of 3×3 optical matrix boards confirm the feasibility of large-size optical switching. Suppressing deviations in the groove position will realize lower loss optical matrix boards in the near future. The apparent roughness of the groove walls can be evaluated simply and effectively by measuring return loss with an interferometric optical-time-domain reflectometer.
