Crystal heat dissipation structure for suppressing temperature drift of electrooptical modulator, and manufacturing method thereof

The invention relates to a crystal heat dissipation structure for suppressing temperature drift of an electrooptical modulator, and a manufacturing method thereof. The heat dissipation of the electrooptical modulator is improved by using the excellent axial thermal conductivity of carbon nanotubes, and meanwhile, by using the excellent light transmittance and electrical conductivity of graphene, electric charges are transferred by using multiple layers of graphene films via conducting resin to suppress the pyroelectric effect of the crystal of the electrooptical modulator, so that the temperature drift caused by the pyroelectric effect of the electrooptical modulator is greatly improved, the use and maintenance cost and frequency of equipment and device are greatly reduced, and the long-term working stability of the device is improved. 本发明涉及一种用于电光调制器温度漂移抑制的晶体散热结构及制作方法，利用碳纳米管优异的轴向导热性能，改善电光调制器散热，同时利用石墨烯优异的透光率和电导率，使用多层石墨烯薄膜通过导电胶传导电荷抑制电光调制器晶体的热释电效应，极大地改善了电光调制器热效应引起的温度漂移，极大地减少了设备装置使用维护成本和频率，提高器件长期工作稳定性。
