Integrated optical apparatus

摘要

An integrated optical apparatus is disclosed that integrates at least two optical devices and can achieve electrical and optical insulation between the optical devices. The integrated optical apparatus includes at least two optical devices both equipped with an optical waveguide, and at least one inner window interposed at a region of the optical waveguide between the optical devices. The inner window disconnects the optical waveguides that are located between the optical devices in order to achieve optical/electrical insulation. According to aspects and embodiments of the present invention, production costs can be reduced because it is not required to employ an independent optical isolator separately in order to achieve optical insulation between the respective optical devices, and process times can be reduced because it is not necessary to control an optical coupling between the optical devices.
