Abstract :
We propose and demonstrate a simple wavelength-tracking technique for the spectrum-sliced wavelength-division-multiplexed passive optical network. The proposed technique could maintain the optical powers of the spectrum-sliced channels within 0.2 dB when the operating temperature of the remote node was varied from 15/spl deg/C to 55/spl deg/C, as rapidly as 0.5/spl deg/C/min.
