nanoLED Wavelength Division Multiplexer Analysis

Conference on Lasers and Electro-Optics, 2019
Optical antennas can enhance the modulation bandwidth and output power of nanoscale LEDs. Here we analyze a wavelength division multiplexer that uses high Q optical antennas in parallel to further increase the total optical power. © 2019 The Author(s)

Wavelength Division Multiplexing Systems and Networks

IETE Technical Review, 1998
Expanding 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 ...

Multichannel wavelength division multiplexing with photonic crystals

Applied Optics, 2001
A 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.

Wavelength division multiplexing of dispersion managed solitons

24th European Conference on Optical Communication. ECOC '98 (IEEE Cat. No.98TH8398), 2002
Periodic 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.

Chaotic wavelength division multiplexing for optical communication

Optics Letters, 2004
We 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.

Stabilization of Soliton Wavelength-Division-Multiplexed Transmissions

Nonlinear Guided Waves and Their Applications, 1996
In 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,

The wavelength division multiplexers for optical telecommunication

Journal of Optics, 1984
Examples of wavelength division multiplexers using multidielectric filters, gratings or both of them, published by different authors, are given. The filter devices are well adapted to the multiplexing of a small number of channels with large distances between wavelengths.

Optical Processor With Wavelength Division Multiplexing

SPIE Proceedings, 1984
We designed an optical processor using wavelength division multiplexing which performs matrix-vector and matrix-matrix multiplications. The Wavelength Division Multiplexing (WDM) Optical Processor can perform analog and digital operations. Its principal advantage over other processors is its parallel architecture that enables high speed calculations.© (

All-fiber dense wavelength division multiplexers

SPIE Proceedings, 1994
Fused and tapered single-mode fiber couplers are used to make polarization insensitive Wavelength Division Multiplexers with a wavelength spacing of around 1 nm. Different structures are presented. As opposed to that of single highly elongated fused couplers, their responses are polarization independent.

Optical fibre wavelength division multiplexing

COMSIG 88@m_Southern African Conference on Communications and Signal Processing. Proceedings, 2003
An 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 ...
