Choose TFLN when:<\/p>\n \n- Maximum modulation bandwidth is required<\/li>\n
- Mature ecosystem and supply chain are preferred<\/li>\n
- Target applications include coherent optics and ultra-high-speed transmission<\/li>\n<\/ul>\n
Choose TFLT when:<\/p>\n \n- Bias stability and low DC drift are critical<\/li>\n
- High optical power handling is required<\/li>\n
- Long-term reliability and thermal robustness are priorities<\/li>\n<\/ul>\n
\nC\u00e2u h\u1ecfi th\u01b0\u1eddng g\u1eb7p<\/h2>\n1. What is the main benefit of TFLN\/TFLT on SiPh compared to silicon modulators?<\/h3>\nThe key advantage is the presence of a strong electro-optic effect, enabling higher bandwidth, lower loss, and lower power consumption than silicon-only modulators.<\/p>\n
\n2. How does evanescent coupling work in hybrid integration?<\/h3>\nLight propagates in the silicon waveguide and partially extends into the thin-film LN or LT layer. This overlapping optical field allows efficient modulation without fully transferring the optical mode.<\/p>\n
\n3. Is this platform suitable for large-scale manufacturing?<\/h3>\nYes. Bonding-based heterogeneous integration allows compatibility with standard silicon photonics fabrication processes, enabling high-volume and cost-effective production.<\/p>","protected":false},"excerpt":{"rendered":" TFLN (Lithium Niobate m\u00e0ng m\u1ecfng) v\u00e0 TFLT (Lithium Tantalate m\u00e0ng m\u1ecfng) tr\u00ean n\u1ec1n t\u1ea3ng Quang t\u1eed
