Notes on Ordering:
[1]. Red Color marked is special order. For operating wavelength beyond stated range, special order can be made with specific coatings. Short Wavelength Bands have lower optical power handling. They use special crystals.
[2]. PM1550 fiber works well for 1310nm.
[3]. High power connector can be ordered separately.
Note:
Opaque: light is blocked without applying a voltage.
Transparent: light goes through without applying a voltage.

Frequently Asked Questions (Q&A)
Q: Can NP device be directly mounted on PCB driver, such as NSDR?
A: NO. NP devices can be operated at high frequency up to 1MHz, but the IL and CT are sensitive to the non-uniformity of temperature across device. So, it is highly recommended to separate the NP device with the driver in a platform such as shown in the following example. The delivery of NPSW with driver will be packaged in the 3D printed platform. The following is one module of NPSW-1x2 & 100kHz of NSDR in a 3D printed platform.
Q: Does NP device drift over time and temperature?
A: NP 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 °C. 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 300V depending on the version.
Q: How does the device work?
A: NP 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: NP 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.
Operation Manual
Basic Setup
- Connect a control signal to the SMA connector on the PCB.
- Attach the accompanied power supply (typically a wall-pluggable unit).
- The device should then function properly.
Note: Do not alter device factory settings.
Application Notes
Fiber Core Alignment
Minimum attenuation depends on excellent core-to-core alignment when connectors are mated. This is crucial for shorter wavelengths with smaller fiber core diameters, as misalignment can significantly increase loss. Connector compatibility between different vendors may also be an issue, especially for angled APC.
Fiber Cleanliness
Fibers with smaller core diameters (<5 µm) must be kept extremely clean. Contamination at fiber-fiber interfaces, combined with high optical power density, can lead to significant optical damage, often requiring re-polishing or replacement of the connector.
Maximum Optical Input Power
Due to small fiber core diameters and high photon energies at short wavelengths, damage thresholds are reduced compared to 1550nm fiber. To prevent damage to fiber end faces and internal components, optical input power should not exceed 20 mW for wavelengths shorter than 650nm. A special version with an expanded core is available for higher power handling.
