筱曉光子 1064nm電光開關使用說明

視頻演示

1.      將光開關模塊上電，散熱系統開始工作；

2.      將1064nm激光從光開關的輸入端接入，此時可以觀測到正向輸出端不通光，反向輸出端通光；

3.      光開關模塊中有一SMA輸入端口，為開關調制信號的輸入端，識別TTL電平。輸入低電平時，光從反向端口輸出，輸入高電平時，光從正向端口輸出。將其與信號源連接，輸入脈沖信號，以視頻中的信號為例：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，與信號源的信號比較。反向輸出端則會得到反相結果；

常見問題解答：

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.
