High-Precision Frequency Difference Locking System for Up/Downstream Lasers with 30 nm Interval in Next Generation Coherent PON.
Optical Fiber Communication Conference (OFC) 2024(2024)
摘要
We demonstrated a high-precision frequency locking system based on asymmetric Mach-Zehnder interferometer (AMZI). The 1526 nm upstream laser realized a frequency difference stability of about 30 nm ± 25 MHz with 1556 nm downstream laser.
