KPT00J20-41S is a compact and versatile polarization modulator developed by the FiberStore company. It has a wide range of applications, including fiber-optic communication, laser and optical test systems, and optical interconnects. In addition, it can be used as a polarization isolator in optical systems.

KPT00J20-41S is an all-fiber device, intended for controlling the polarization state of light in transmitting and receiving systems. It is an integrated, cost-effective solution, providing polarization control at transmission line level. Its core is an electro-optic modulator, which is driven by an integrated driver. The modulator works in both the linear and circular polarization modes, and can achieve up to 90° polarization modulation.

The working principle of KPT00J20-41S is based on the polarization-dependent losses (PDL). This modulator uses a electro-optic crystal, such as lithium niobate, to implement PDL. The crystal and the electrodes are vapor-deposited between two layers of fiber. The electro-optic crystal creates a refractive index variation, which increases with the applied voltage. This variation can be used to control the polarization state of light passing through the crystal.

In application, the KPT00J20-41S modulates the polarization of light using an applied electric field. This electric field is typically generated by an AC signal. The AC frequency, modulation range and modulation depth are programmable, and can be adjusted according to the specific application. The modulated light is then used for communication, monitoring, or control.

The KPT00J20-41S is a versatile and reliable device, with advantages such as low power consumption, low cost, and low insertion loss. It is suitable for a variety of applications, ranging from fiber-optic systems to optical instrumentation and communication. It is a valuable component for a variety of industries, from telecommunications to medical instrumentation.
