Embodiment 1

[0046] ① Accurately weigh the raw materials according to the above formula and mix them evenly.

[0047] ②The mixture is put into a platinum crucible and melted in a silicon carbon rod electric furnace at 1250°C

[0048] ③ After the glass is melted, it is stirred under an oxygen atmosphere.

[0049] ④Stop ventilation, clarification and homogenization, then cool the glass to 1000°C and pour it into a preheated mold.

[0050] ⑤Quickly put the glass into the muffle furnace whose temperature has been raised to 520°C. After holding the temperature for 2 hours, anneal at a speed of 10°C / hour to about 250°C, and then anneal at a speed of 20°C / hour to 100°C. Turn off the muffle furnace and cool down to room temperature.

[0051] The preparation process of Examples 2, 3, and 4 is similar to that of the first example, and the melting temperature and annealing temperature are determined according to the glass components.

[0052]We further fabricate planar waveguides in the fabricated...

Abstract

A preparing process of optical waveguide of phosphate glass, containing two steps. First, melting phosphate glass with erbium. Second, preparing optical waveguide using the glass by the way of ion exchange. The chemistry proerty of it is stability. It contains good surface optical quality in the process of ion exchange. Surface of optical waveguide refractive index delta n is 0.005-0.04. Transmit loss of wave-guide is under 1dB/cm. Waveguide laser and orthoron made from the glass is valuable of application in the field of telecommunication.

Description

technical field [0001] The invention relates to phosphate glass, in particular to a method for making a phosphate glass optical waveguide. Background technique [0002] Erbium atoms provide gain over the 1550nm optical communication window. In order to meet the demand for high integration, high performance and low price devices in the "metropolitan area network" market, optical communication devices are developing in the direction of miniaturization and integration. The optical waveguide structure can confine the pump light energy in a region with a very small cross-sectional area and a long length, thereby increasing the pump light power density and effective length of action, and obtaining a very high laser gain per unit length, which is about 100 times that of the fiber structure. times. Compared with erbium-doped fiber amplifiers, erbium-doped glass waveguide amplifiers have the characteristics of low manufacturing cost, high gain per unit length, compact structure, sm...
