Implication

Experimental demonstration shows rapid optical stabilization in a 4×2.5 Gb/s cold-start WDM system, indicating reliable automated laser locking.

Key Points

Demonstrate an automated cold-start wavelength division multiplexing (WDM) architecture using a synchronized etalon filter for fast laser stabilization.
Configured a 4×2.5 Gb/s WDM system utilizing a synchronized etalon filter to control transmitter lasers across designated standardized channels.
Assessed system startup time, frequency locking accuracy at intervals of 1547.82 + n × 0.8 nm (193.686 − n × 0.100 THz), and simultaneous power regulation.
Transmitter lasers locked automatically to the standardized optical grid with a frequency accuracy within 1 GHz.
Output optical power for each channel was regulated simultaneously to 0 ± 0.1 dBm.
Achieved error-free transmission (bit error rate < 10^-9) across all channels within 20 s of powering on the system.
