Do you know the density effect of nonlinear light guide on optical quartz glass?

        Optical quartz glass uses photolithography and ion exchange technology to produce low-loss nonlinear optical waveguides, which can prepare small-sized and dense ultra-fast full-light-speed modulation integrated optical waveguide devices, which are information highway communication networks based on ultra-large-scale data transmission and processing. Rapid processing of information and increased capacity provide a practical element. Nonlinear optical materials and devices have become photonics microstructures and new types. Density of Glass The density of optical glass is one of the basic physical properties that users and manufacturers must understand. In addition, the density data is also required to calculate the molecular volume and molecular refraction of the glass. 1. Determination method of glass density The commonly used methods for determining the density of solid glass are the weight loss method and the pycnometer method. The density of molten glass was measured by platinum ball weight loss method. Drainage weight loss method. Pycnometer method. If there are a lot of bubbles in the glass sample, it is difficult to obtain accurate results by using the above method, and it must be determined by the pycnometer method. Due to the influence of nonlinear light guide on the density of optical quartz glass, at this time, put the crushed glass powder into a pycnometer containing distilled water or other organic liquids, and put the pycnometer into a vacuum chamber to remove the adhesion on the glass surface. air, and then analyze the density of 51.3-4 glass on the balance and weigh it. The obtained results are calculated according to the following formula for glass density: set --- the next m- (Lu - 0.0012) + O. OOt2 (1.3-11) f01 ten fn——fn2: in the formula o:——glass weight (g)
