Abstract :
We have demonstrated an effective spectral linewidth suppression of commercial TLS using long cavity, narrow bandwidth SBS filter and multi frequency-selection mechanism. Measured linewidth suppression from ~3MHz to less than 20kHz is successfully achieved with a significant SMSR improvement of ~20dB over 30nm range in C-band.
