Micro PBS separates a laser beam into two different
polarization beams. Micro PBS is generally used in
fiber optical communication as the core component of
polarizer,
polarization beam combiner, and interleaver.
Features
- Low Polarization Dependent Loss
- Low Insertion Loss
- Low PMD
- Environmentally Stable
Applications
- Polarization Beam Combiner
- Raman Amplifier
- Circulators
- Interleavers
