Coupled-mode analysis of fiber-optic add drop filters for dense wavelength-division multiplexing [PDF]
Optics Letters, 1997 We present a coupled-mode theory of fiber-optic add drop filters, which involve directional coupling between two fibers combined with fiber Bragg gratings defined inside the coupling region.

Quantum key distribution integration with optical dense wavelength division multiplexing: a review
IET Quantum Communication, 2020 Quantum key distribution (QKD) can ensure information security between two remote parties. To commercialise QKD technology successfully, it should be integrated with dense wavelength division multiplexing optical transport.

Quantum key distribution for 10 Gb/s dense wavelength division multiplexing networks [PDF]
Applied Physics Letters, 2014 We demonstrate quantum key distribution (QKD) with bidirectional 10 Gb/s classical data channels in a single fiber using dense wavelength division multiplexing. Record secure key rates of 2.38 Mbps and fiber distances up to 70 km are achieved.
