Abstract
Optical device to optically connect an outside optical fiber with an optical waveguide through the connecting medium of an optical fiber with ferrule located within the hole of the optical receptacle that is fixed at the optical waveguide. The optical waveguide and the outside optical connectors are optically connected with high accuracy and small optical loss. Because no damage is caused to the optical waveguide by attachment or removal of the optical connectors, the optical performance of the optical device is not reduced.
