GaInNAs microspheres for wavelength division multiplexing
IEE Proceedings - Optoelectronics, 2003The GaInNAs range of compounds is suitable for optoelectronic device applications in 1.3 and 1.55 µm lasers, because of the large conduction band discontinuity resulting in good electron confinement and improved temperature characteristics. GaInNAs is suited to wavelength division multiplexing (WDM) applications in high-speed optical communication ...

Dual mode and wavelength-division multiplexing
Frontiers in Optics 2015, 2015Simultaneous mode and wavelength division multiplexing is proposed using integrated asymmetric directional coupler and multimode interference waveguide. Using numerical simulations, the device exhibits low insertion loss of 1.2dB and a cross-talk of -18dB.

Massive wavelength-division multiplexing with solitons
IEEE Journal of Quantum Electronics, 1998Solitons have already enabled the demonstration of many-channel wavelength-division multiplexing (WDM), error free over transoceanic distances, at per-channel rates of 10 and 20 Gbit/s. In this paper, we assess the potential for extending the total transmission rate to many hundreds of gigabit/s in such massive WDM with solitons.

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 ...

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

Wavelength Division Multiplexing Systems and Networks
IETE Technical Review, 1998Expanding the channel capacity is the pressing need of today's communication systems. Multiplexing is the technique of combining channels to achieve this without interference. Wavelength-division-multiplexed (WDM) systems and networks are currently being investigated for optical data transmission in telecommunication and computer local area networks ...

<title>Compact wavelength division multiplexers and demultiplexers</title> [PDF]
SPIE Proceedings, 2000 Compact 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 demultiplexer for a wavelength division multiplexing system
Applied Optics, 1979A wavelength division multiplexing (WDM) technique, which transmits signals with different wavelengths by means of a single optical fiber, can increase the capacity of optical fiber transmission systems. This paper describes the experimental results of a demultiplexer using a diffraction grating for a WDM system. The insertion loss of the demultiplexer

Wavelength division multiplexed soliton transmission with filtering
Optics Communications, 1994Abstract We present a theoretically study on the timing jitter induced by the interaction between solitons propagating in two wavelength separated channels of a long-haul fiber transmission system. We show that the inclusion of in-line filters almost suppresses the arrival time jitter even when the collision length is on the order of the amplifier ...
