Ultra-thin polyimide wave plate

Thin wave plate suitable for optical circuits

Made of polyimide, it has excellent heat resistance and chemical resistance that can withstand soldering work.
In addition, the material itself has a chemical structure that suppresses absorption at communication wavelengths, making it ideal for use in optical circuits (PLC).
Modulators (Mach-Zehnder, QPSK) and low-loss optical circuit implementation on AWG are possible.

feature

• Low insertion loss
• High heat resistance to withstand soldering work
• Since it is thin and easy to handle, it is ideal as a wave plate to be inserted into an optical circuit.

Application Examples

Examples of application to AWG

Examples of applications to integrated optical circuits

Because of its small size, wavelength plates with different optical axes can be placed in close optical paths, opening up the possibility of application to highly functional integrated optical circuits.

Example of polarization conversion for multiple ports

It can also be applied to polarization conversion in multi-port optical circuits, such as multi-fiber connectors (MTs) and WSS front-ends.

Examples of application to wavelength multiplexers and demultiplexers, and the effect of eliminating polarization dependence by using waveplates.
