Optical amplifiers can be used to increase the distribution of analogue video signals over a
passive optical network. The paper analyses the gains in system loss budget that can be …

We report on 1< cd0215f. gif> N branching devices for fiber-optic networks. A novel Y-
pattern mask for loss reduction in branching waveguide has been investigated based on …

A low-loss Y-branch optical waveguide with a wide gap between two output waveguides
was designed. Its performance was simulated by the beam propagation method. In spite of …

This thesis is mainly concerned with the use of semiconductor optical amplifiers (SOAs) in
wavelength division multiplexed (WDM) broadcast topologies viz. star and tree. The aim of …

Optical circuits based on low-loss glass waveguide on silicon are a practical and promising
approach to integrate different functional components. Fiber attachment to planar waveguide …

Integrated optical quantum circuits based on photonic waveguiding structures are
increasingly gaining attention as a possible solution for scalable quantum technologies with …

Optical switches are important for applications in optical communications and photonic
integrated circuits (PICs) to allow for selection of optical paths. In this work, a thermo-optic …

British Telecom's telephony on passive optical network (TPON) system already supports
fiber to the curb (FTTC) through Street TPON. TPON also provides a reference for the …
