Microphotons 1064nm Electro-Optical Switch Instructions

1. Power on the optical switch module and the cooling system starts working;

2. Connect the 1064nm laser to the input end of the optical switch. At this time, it can be observed that the forward output end does not pass light, but the reverse output end passes light;

3. There is an SMA input port in the optical switch module, which is the input end of the switch modulation signal and recognizes the TTL level. When the input is low level, the light is output from the reverse port, and when the input is high level, the light is output from the forward port. Connect it to the signal source and input the pulse signal. Take the signal in the video as an example: frequency 2MHz, high level 1.6V (output impedance 50 ohms), low level 0V, pulse width 100ns;

4. Connect PD to the forward output end to collect the pulse light signal and compare it with the signal of the signal source. The reverse output end will get an inverted result;

F&Q

Q: DoesNSdevice drift overtime 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 tempera- ture-dependent birefringence,Vp,temperature gradient,optical power,at resonance points (electron- ic). 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: 100to400V depending on the version.

Q: How does the device work?

A:NS devices are not based on Mach-Zander Interference,rather birefringence crystal’snature 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 imple- mentation 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 con- sumption.
