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 systems and networks [PDF]
Proceedings of LEOS '93, 2002 Summary form only given. Optical Wavelength Division Multiplexing (WDM) has emerged as an extremely flexible and efficient technique for accessing the vast optical fiber bandwidth. It also allows the provision of various services and flexible upgrading in optical networks.

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 ...

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 ...

Multichannel wavelength division multiplexing with photonic crystals
Applied Optics, 2001A multichannel wavelength-division-multiplexing system consisting of a two-dimensional photonic crystal is proposed. The system consists of two parts, a waveguiding element, realized by defects in a photonic crystal, and frequency-selective elements, realized by photonic crystal microcavities.

Chaotic wavelength division multiplexing for optical communication
Optics Letters, 2004We demonstrate wavelength division multiplexing with chaotic subcarriers in two pairs of one-way-coupled Nd:YVO4 microchip lasers. Two individual digital messages are encoded on two chaotic carriers with different wavelengths in two transmitters by the chaotic masking method, and the mixed signals are sent to two receivers.

Wavelength division multiplexing of dispersion managed solitons
24th European Conference on Optical Communication. ECOC '98 (IEEE Cat. No.98TH8398), 2002Periodic dispersion compensation largely widens the transmission bandwidth of solitons with enhanced power. Soliton interactions and collisions in a wavelength-division-multiplexed system may however set important limitations to the channel spacing.

Stabilization of Soliton Wavelength-Division-Multiplexed Transmissions
Nonlinear Guided Waves and Their Applications, 1996In this work, we consider the bandwidth limitations in soliton wavelength-division-multiplexed (WDM) transmission systems [1, 2]. The present analysis suggests different methods to overcome two of the main sources of instability that limit the available optical bandwidth, namely third-order dispersion (TOD) and resonant soliton-soliton collisions [6, 4,
