Problems solved by technology

like Figure 1A and 1B As shown, the total injection loss of the device is significantly increased due to the fact that all the core regions in the waveguide containing the electrode 130 are composed of nonlinear optical polymers with higher optical losses than linear optical polymers.

Abstract

A low-loss optically active device and a manufacturing method therefor are provided. The method includes the steps of: forming a lower clad layer using linear polymer on a substrate capable of transmitting ultraviolet (UV) light, forming a first metal layer through which the UV light does not transmit at a region on the lower clad layer, forming a second metal layer which the UV light does not transmit, forming a non-linear polymer layer, forming the non-linear polymer cured at only the non-linear core region by exposing the UV light to the substrate, forming a third metal layer, removing the second metal layer, coating linear polymer on the first metal layer and optical waveguide, forming the linear polymer at only the linear core region, removing the first metal layer and the third metal layer, and forming an upper clad layer on the lower clad layer and waveguide core region.

Description

technical field [0001] The present invention relates to an optical device and a manufacturing method thereof, and more particularly, to a low-loss optical active device, which can reduce the optical density of the device by injecting a nonlinear optical polymer only into the waveguide region where the nonlinear effect occurs. Waveguide loss, and fabrication methods involving the device. Background technique [0002] Generally, when optical polymers are used to form optically active devices such as optical modulators or optical switches, the optical waveguide formed in the device consists of a cladding region and a core region. Typically, in forming an optically active device from an optical polymer, the waveguide core of the device is formed from an organic polymer having nonlinear properties. [0003] However, if the entire waveguide core forming the device is composed of nonlinear optical polymer, the overall loss characteristics of the device will be degraded. The waveg...
