Abstract

본 발명은 광의 손실이 적은 석영유리 도파로에 높은 전기광학 특성을 부여하고 고속 및 저손실의 석영유리 도파로의 제조를 가능하게 하여 종래 석영유리 도파로가 각종 고속의 광소자들에 응용될 수 없었던 한계를 극복한 것이다. 따라서, 본 발명은 위상변조기를 비롯하여 광스위치, 광간섭기, 편광조절기 등의 각종 광부품들에 매우 유용하게 적용될 수 있다. 또한, 종래 석영유리 도포로가 갖는 응력유기 복굴절율에 의한 편광이방성 문제를 제거할 수 있다.The present invention provides high electro-optical properties to quartz glass waveguides with low light loss and enables the production of high-speed and low-loss quartz glass waveguides, thereby overcoming the limitations that conventional quartz glass waveguides could not be applied to various high-speed photonic devices. It is. Therefore, the present invention can be very usefully applied to various optical components such as an optical switch, an optical interferometer, a polarization controller, including a phase modulator. In addition, the problem of polarization anisotropy due to the stress organic birefringence of the conventional quartz glass coating furnace can be eliminated.
