ABSTRACT:
Prior art wavelength lockers used in tunable laser systems can provide information to ensure that the laser is locked onto a channel, but do not provide information as to which specific channel the laser is locked onto. Embodiments of the present invention include a wavelength locking channel monitor that provides a servo-locking error signal and a channel-identifying signal to allow a tunable laser to be updated to lock to the proper channel. Embodiments of the present invention include wavelength-dependent periodic and/or monotonic filters, which provide monotonically variable finesse and a monotonically variable transmission. Embodiments of the present invention also extracts amplitudes, phases, frequency, and/or modulation depths from a dither introduced in an incident light beam to determine the laser channel and the laser mode within that channel.
