Temperature Insensitive Arrayed Waveguide Grating Multiplexer for Optical Property Compensation and The Manufacturing Method Thereof

일반적인 광도파로열 격자(AWG: Arrayed Waveguide Grating)회로 소자는 온도 환경의 변화에 따라 그 중심파장이 변한다. 이러한 광도파로열 격자회로의 온도변화에 따른 중심파장의 변화를 외부 전원의 공급 없이 수동적으로 보상해 주기 위하여 광도파로열 격자회로 소자의 제1입력도파로와 슬랩도파로의 경계부분을 절단하고 열팽창계수가 큰 이송용 자재를 부착하여 제1입력도파로로부터 슬랩도파로로의 광신호가 입력되는 위치를 수동적으로 조정함으로써 광도파로열 격자회로가 가지고 있는 중심파장의 온도 의존성을 상쇄시킬 수 있으며, 이를 온도무의존 광도파로열 격자(Temperature Insensitive AWG) 소자라 칭한다. 절단 공정에서 필수적으로 절단날의 두께에 해당되는 일정부분이 제거될 수밖에 없으며, 이는 온도무의존 광도파로열 격자회로 소자의 특성, 특히 3dB 대역폭 변화에 영향을 미친다. 본 발명은 온도무의존 광도파로열 격자회로 소자의 제작 과정에서 발생하는 절단폭에 의한 광로길이의 변화 부분을 보상하기 위하여 광도파로열 격자회로의 설계 과정에서 절단폭에 의한 특성변화에 해당되는 광로길이 만큼 추가적으로 길이를 보상하여 절단 이후에도 특성의 변화가 최소화 되도록 하는 방법과 절단폭 부분 만큼 옮겨진 위치에 추가적으로 별개의 제2입력도파로를 구성하여 절단 후 제2입력도파로를 사용함으로써 절단에 따른 광로길이의 변화를 최소화 하여 온도무의존 광도파로열 격자회로 소자의 특성 변화를 보상한다. In general, an arrayed waveguide grating (AWG) circuit device changes its center wavelength according to a change in temperature environment. The thermal expansion coefficient is cut by cutting the boundary between the first input waveguide and the slab waveguide of the optical waveguide grating circuit element in order to manually compensate for the change in the center wavelength according to the temperature change of the optical waveguide grating circuit without supplying external power. By attaching a large conveying material and manually adjusting the position where the optical signal from the first input waveguide to the slab waveguide is inputted, it is possible to offset the temperature dependence of the center wavelength of the optical waveguide thermal lattice circuit, which is independent of temperature. It is called a Waveguide Thermal Grating (Temperature Insensitive AWG) device. In the cutting process, a certain portion corresponding to the thickness of the cutting edge is essentially removed, which affects the characteristics of the temperature-independent optical waveguide grating circuit element, especially the 3dB bandwidth change. The present invention provides an optical path corresponding to a characteristic change due to ...
