OPTICAL MODULE, OPTICAL BRANCH INSERT DEVICE, AND OPTICAL TRANSMISSION DEVICE

Title:

OPTICAL MODULE, OPTICAL BRANCH INSERT DEVICE, AND OPTICAL TRANSMISSION DEVICE

Document Type and Number:

WIPO Patent Application WO/2004/008220

Kind Code:

A1

Abstract:

An optical module (1) has a flat waveguide (2). On this flat waveguide (2), there are arranged an optical circuit (3) for an optical switch formed by 2 × 2 cross optical waveguides A₁ to D₁ and an optical circuit (4) for an optical variable attenuator formed by 2 × 2 cross optical waveguides A₂ to D₂. On the flat waveguide (2), an actuator structure (5) is attached. This actuator structure (5) includes an actuator section (6) for the optical switch and an actuator section (7) for the optical variable attenuator. The optical circuit (3) of the flat waveguide (2) and the actuator section (6) constitute the optical switch (8) while the optical circuit (4) of the flat waveguide (2) and the actuator section (7) constitute the optical variable attenuator (9).
