A multiple-wavelength GaInAsP/InP microlaser with microdisk radiuses from 10 m to 10.6 m laterally coupled into a bus waveguide are fabricated by standard photolithygraphy and inductively coupled-plasma (ICP) etching techniques. The lasing wavelengths are 1533 nm, 1541 nm, 1551 nm and 1555 nm at the CW injection current of 10 mA for the four microlasers. The proposed multiple-microlaser array w...

We propose and demonstrate 10-Gb/s broadcast signal transmission in a wavelength-division-multiplexing passive optical network (WDM-PON) by employing a modular-type mutually injected Fabry-Perot laser diodes (MI F-P LDs) as a cost-effective multi-wavelength light source (MWS). We introduce a simple interferometric noise suppression technique with proper electrical filtering to improve transmiss...

The paper deals with fairness issues in a slotted, single-hop, WDM (Wavelength Division Multiplexing) optical architecture, based on a folded bus topology, previously proposed as a broadband access system or as a metro network. The peculiar fairness problem arising in this folded bus based architecture is addressed and an extension of the MetaRing protocol to the WDM scenario, named Multi-MetaR...

Recently, metropolitan and access communication networks have markedly developed by utilizing a variety of technologies.

Thin film multilayer narrow bandpass interference filters are widely used in wavelength division multiplexing (WDM) applications in fibre optic communication systems. These filters must have sharp cut-on and cut-off on either side of the passband and practically zero transmittance outside the passband, over the wavelength range of the application. In an effort to demonstrate the feasibility of ...

Multi-domain wavelength-division multiplexing (M-WDM) is proposed as a generalization of single star-coupled WDM networks. The objective is to provide scalable interconnection schemes for different parallel computer architectures that utilize the multi-channel and tunability characteristics of photonic network devices, given their existing limitations. Device tunability results in reconfigurabl...

The bandwidth requirements of the Internet are increasing every day and there are newer and more bandwidththirsty applications emerging on the horizon. Wavelength division multiplexing (WDM) is the next step towards leveraging the capabilities of the optical fiber, especially for wide-area backbone networks. The ability to switch a signal at intermediate nodes in a WDM network based on their wa...

We propose a spectral efficient radio over wavelength division multiplexed passive optical network (WDM-PON) system by combining optical polarization division multiplexing (PDM) and wireless multiple input multiple output (MIMO) spatial multiplexing techniques.
