Compact wavelength division multiplexers and demultiplexers
Applied Optics, 2002Compact devices for wavelength division multiplexing and demultiplexing, believed to be novel, are presented. These devices are based on planar optics configurations, comprising multiplexed diffractive optical elements. The principle, design, and recording of these planar devices are described, including the fact that the recording is done at a single ...

Optical fiber wavelength division multiplexing
IEEE Aerospace and Electronic Systems Magazine, 2003During flight, aircraft avionics transmit and receive RF signals to/from antennas over coaxial cables. As the density and complexity of onboard avionics increases, the electromagnetic interference (EMI) environment degrades proportionately, leading to decreasing signal-to-noise ratios (SNRs) and potential safety concerns.

Monomode Wavelength Division Multiplexer/Demultiplexer
SPIE Proceedings, 1986In this paper we describe an in-line single-mode fiber optic wavelength division multiplexer/demultiplexer designed to operate at 1.32 um and 1.55 um. This device was fabricated using evanescent wave coupler technology and consequently exhibits an insertion loss on the order of 0.05 db and a high degree of stability with regard to changes in ...

Optical fibre wavelength division multiplexing
COMSIG 88@m_Southern African Conference on Communications and Signal Processing. Proceedings, 2003An overview is given of wave-length division multiplexing (WDM) as a means of expanding communication capacity and implementing special data techniques in a fiber-optic system. This technology is implemented by adding optical sources of different wavelengths at optical transmitting locations, then mixing (multiplexing) the optical signals and coupling ...

Wavelength-Division Multiplexing Optics
2017Wavelength-division m ultiplexing (WDM) multiplies transmission capacity by allowing a single optical fiber to carry separate signals at multiple wavelengths, but that benefit comes at a cost in complexity. Additional optical components are needed to combine and separate optical channels at closely spaced wavelengths, and to process the signals as they
