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.
