High-Precision Frequency Difference Locking System for Up/Downstream Lasers With 30 nm Interval in Next Generation Coherent PON (W2A.25)
Presenter: zifeng chen, Huazhong University of Science and Technology
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.
