Bidirectional Single Fibre Links for Base Station Remote Antenna Feeding (2007)

Guido Steiner, Werner Baechtold, Stephan Hunziker

Abstract. In this contribution the feasibility and performance of low-cost bidirectional single fibre links for analogue RF fibre-optic (FO) antenna feeding are investigated. Wavelength division...

Session: RF Photonics for CATV and HFC Systems (28-30 July) Reduction of 3 rd Order Intermodulation of a Semiconductor Laser by an Adaptive Low-Cost Predistortion Circuit at 1.8 GHz (2007)

Low-cost Predistortion, Circuit Ghz, Zip Ch, Guido Steiner, Stephan Hunziker, Werner Baechtold

Abstract: A low-cost adaptive predistortion circuit to reduce 3 rd order intermodulation of semiconductor lasers has been designed. Using a microcontroller to adjust the control voltages the...

Quasi-analytic steady-state solution of VCSEL rate equations including spatial hole burning and carrier diffusion losses (2003)

Marc Jungo, Daniel Erni, Werner Baechtold

this paper. The analytic calculation of the steady-state solution of rate equations without lateral dependency is trivial [9], but cannot be performed directly for spatially-dependent models, due...

2-D VCSEL Model for Investigation of Dynamic Fiber Coupling and Spatially Filtered Noise (2003)

Marc Jungo, Daniel Erni, Werner Baechtold

We propose a set of transformed two-dimensional (2-D) rate equations, which allow the computation of dynamic gain competition resulting from inhomogeneous field and carrier spatial distributions...
