筱晓光子 1064nm电光开关使用说明

视频演示

1.      将光开关模块上电，散热系统开始工作；

2.      将1064nm激光从光开关的输入端接入，此时可以观测到正向输出端不通光，反向输出端通光；

3.      光开关模块中有一SMA输入端口，为开关调制信号的输入端，识别TTL电平。输入低电平时，光从反向端口输出，输入高电平时，光从正向端口输出。将其与信号源连接，输入脉冲信号，以视频中的信号为例：频率2MHz、高电平1.6V（输出阻抗50欧）、低电平0V、脉宽100ns；

4.      在正向输出端连接PD采集脉冲光信号，与信号源的信号比较。反向输出端则会得到反相结果；

常见问题解答：

Q: Does NS device drift over time and temperature?

A: NS devices are based on electro-optical crystal materials that can be influenced to a certain range by the environmental variations. The insertion loss of the device is only affected by the thermal expansion induced miss-alignment. For extended temperature operation, we offer special packaging to -40 -100 0C. The extinction or cross-talk value is affected by many EO material characters, including temperature-dependent birefringence, Vp, temperature gradient, optical power, at resonance points (electronic). However, the devices are designed to meet the minimum extinction/cross- talk stated on the spec sheets. It is important to avoid a temperature gradient along the device length.

Q: What is the actual applying voltage on the device?

A: 100 to 400V depending on the version.

Q: How does the device work?

A: NS devices are not based on Mach-Zander Interference, rather birefringence crystal’s nature beam displacement, in which the crystal creates two different paths for beams with different polarization orientations.

Q: What is the limitation for faster operation?

A: NS devces have been tested to have an optical response of about 300 ps. However, practical implementation limits the response speeds. It is possible to achieve a much faster response when operated at partial extinction value. We also offer resonance devices over 20MHz with low electrical power consumption.
