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 devices 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.
