The commonly used confinement factor-based formula for modal gain in amplifying waveguides – gmod=Γgmat, with Γ a confinement factor – is well established and accurate for TE modes. The TM case is rarely, and sometimes erroneously, described in

The mode expansion propagation method is a modelling technique for a large variety of waveguide components. Until now only the case with TE modes has been reported; we give details on the mode expansion propagation method for TM modes. Instead of one

In this paper we propose the monolithic integration of quantum well InGaAs/GaAs 0.98 μm lasers with passive mode-size convertors using the shadow-masked growth technique. The full width at half maximum (FWHM) of the far-field in the transverse direc

Efficient coupling of light from a semiconductor waveguide to an optical fiber is difficult to achieve due to the inherent differences in the spot sizes. The problem is particularly severe in the vertical dimension. The use of a uniform, untapered, i

A well known characteristic of optical fibres is that they do not maintain the polarisation of the transmitted light. Therefore an important requirement of integrated optical circuits in optical fibre systems is that they have to be polarisation inde

For a number of optoelectronic components it is important to estimate the amount of waveguide birefringence in order to reduce or eliminate a possible polarization dependence. Several important structures (e.g. buried or ridge) can be analysed with s

It has been shown recently that the mode expansion propagation method [1][2] is an interesting alternative for conventional beam propagation algorithms [3]-[5] to model light propagation in optical waveguides. The method has proved to be fast and acc

Improvement of chip to fiber coupling is a major issue for practical applications Of OEICs. We have previously shown that the use of a multimode coupler can significantly improve the coupling efficiency [1,2]. In spite of the potentially very high co

Grating assisted codirectional couplers are very useful for widely tunable lasers and filters. They consist of a directional coupler with periodic discontinuities. These have to be strong to obtain coupling in relatively short devices. Therefore thes
