Crystro High Quality Lithium Niobate LiNbO3 LN Single Crystals
Lithium niobate (LN), an outstanding and versatile material, has influenced our daily life for decades: from enabling high-speed optical communications that form the backbone of the Internet to realizing radio-frequency filtering used in our cell phones. This half-century-old material is currently embracing a revolution in thin-film LN integrated photonics. The success of manufacturing wafer-scale, high-quality, thin films of LN on insulator (LNOI), accompanied with breakthroughs in nanofabrication techniques, have made high-performance integrated nanophotonic components possible.
Crystro provides:
- LiNbO3 wedges used for fiber optical isolators and circulators.
- Reliable delivery
- Strict quality control
- Technical support
- Very competitive prices
LiNbO3 Crystal Applications:
1. Pockels Cells
2. Q-switches
