US 7054517 B2Abstract
An apparatus comprises: a planar optical waveguide having sets of locking diffractive elements and means for routing optical signals; and corresponding lasers. Lasers launch signals into the planar waveguide that are successively incident on elements of the locking diffractive element sets, which route fractions of the signals back to the lasers as locking feedback signals. The routing means route between lasers and output port(s) portions of those fractions of signals transmitted by locking diffractive element sets. Locking diffractive element sets may be formed in channel waveguides formed in the planar waveguide, or in slab waveguide region(s) of the planar waveguide. Multiple routing means may comprise routing diffractive element sets formed in a slab waveguide region of the planar waveguide, or may comprise an arrayed waveguide grating formed in the planar waveguide. The apparatus may comprise a multiple-wavelength optical source.

An optical apparatus comprises: i) a planar optical waveguide having at least one set of locking diffractive elements and at least one corresponding means for routing an optical signal; and ii) at least one corresponding laser. The planar optical waveguide substantially confines in at least one transverse spatial dimension optical signals propagating therein. Each corresponding laser is positioned so as to launch a corresponding laser optical signal into the planar optical waveguide so that the corresponding laser optical signal is successively incident on the diffractive elements of the corresponding locking diffractive element set. Each locking diffractive element set routes within the planar optical waveguide a fraction of the corresponding laser optical signal back to the corresponding laser with a corresponding locking transfer function. The fraction of the laser optical signal thus routed serves as a corresponding locking optical feedback signal, thereby substantially restricting the corresponding laser optical signal to a corresponding laser operating wavelength range, determined at least in part by the corresponding locking transfer function of the corresponding locking diffractive element set. Each corresponding routing means routes within the planar optical waveguide, between the corresponding laser and a corresponding output optical port with a corresponding routing transfer function, at least a portion of that fraction of the corresponding laser optical signal that is transmitted by the corresponding locking diffractive element set. The optical apparatus may comprise multiple lasers, multiple corresponding locking diffractive element sets, and multiple corresponding routing means, thereby comprising a multiple-wavelength optical source.
