筱曉光子 1064nm電光開(kāi)關(guān)使用說(shuō)明
視頻演示
1. 將光開(kāi)關(guān)模塊上電，散熱系統(tǒng)開(kāi)始工作；
2. 將1064nm激光從光開(kāi)關(guān)的輸入端接入，此時(shí)可以觀測(cè)到正向輸出端不通光，反向輸出端通光；
3. 光開(kāi)關(guān)模塊中有一SMA輸入端口，為開(kāi)關(guān)調(diào)制信號(hào)的輸入端，識(shí)別TTL電平。輸入低電平時(shí)，光從反向端口輸出，輸入高電平時(shí)，光從正向端口輸出。將其與信號(hào)源連接，輸入脈沖信號(hào)，以視頻中的信號(hào)為例：頻率2MHz、高電平1.6V（輸出阻抗50歐）、低電平0V、脈寬100ns；
4. 在正向輸出端連接PD采集脈沖光信號(hào)，與信號(hào)源的信號(hào)比較。反向輸出端則會(huì)得到反相結(jié)果；

常見(jiàn)問(wèn)題解答：
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.
