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

Half-wave plate (model: AT-HWP)

Quarter wave plate (model: AT-QWP)

Application example

Application example to AWG

Example of application 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

An example of customized shape

Example of front-end application of WSS (Wavelength Selective Switch)

Example of application to a wavelength multiplexer/demultiplexer and the effect of eliminating polarization dependence by using a wave plate
