Despite the major advances in health psychology over the past decade and the changes that have taken place in the Canadian health sector, there remains a paucity of information available about the structure of psychological services in Canadian healt

The operation of 1.48-/spl mu/m flared resonators is thoroughly studied, both experimentally and theoretically: the accurate determination of threshold condition as a function of geometrical and material parameters, the study of emission spectra and

We demonstrate an easy and efficient step tunable sampled fiber Bragg grating (SFBG) external cavity laser. A small current variation applied to a single electrode induces a step tuning of 15 nm based on the Vernier effect between an SFBG with a comb

We demonstrate the relevance of ion implantation of the multiple quantum-well active layer in unstable-cavity lasers as a means of efficiently filtering the parasitic higher order waves by introducing additional propagation loss within the cavity. Se

A 1.48-/spl mu/m unstable-cavity laser is coupled into single-mode fiber using three microlenses. Reproducible coupling of very high power is demonstrated with different types of lenses (plano-convex or biconvex, with different apertures). Over 550 m

Diffraction-limited high-power devices may suffer from self-focusing effects due to nonuniform gain saturation. In this letter, we propose the concept of the distributed electrode, which allows one to improve the modal behavior of these lasers and to

An optical self-aligned flip-chip packaging technique for tilted semiconductor optical amplifier arrays is reported. It uses a Si motherboard with V-grooves for self-alignment between the tilted SOA array and angle polished fibre arrays. Fibre-to-fib

A current variation less than 3 mA applied to a single electrode induces a step tuning of 15 nm in a sampled fiber Bragg grating external cavity laser. The output power is 6 dBm and side mode rejection -40dB.

Using a tapered in width square active waveguide and bulk InGaAsP/InP material we demonstrate a polarisation independent amplifier structure operating at 1550 nm with a reduced far-field divergence. Improvement of coupling efficiency enables us to ac
