Abstract :
We propose a novel tunable-filter configuration for optical C/D/C drop in ROADMs, which achieves low insertion loss and low power consumption. A prototype is monolithically fabricated with PLC technologies and its good filtering performance is experimentally confirmed by BER measurement.
