Broadband Single-Transverse-Mode Fluorescence Sources Based on Ribs Fabricated in Pulsed Laser Deposited Ti:Sapphire Waveguides
Popis výsledku v původním jazyce
Active rib waveguides with depths and widths varying from 3 to 5 ľm and from 9 to 24 ľm, respectively, have been structured by Ar<sup>+</sup>-beam etching in pulsed laser deposited Ti:sapphire layers. Losses in the channel structures were essentially atthe same levels as the unstructured planar waveguide host, therefore suggesting that there is no significant additional contribution to loss from the rib-fabrication procedure. Measurements of the beam-propagation factors, M<sub>x</sub><sup>2</sup> and M<sub>y</sub><sup>2</sup>, indicate single-transverse-mode fluorescence emission. The fluorescence output power was in the order of 300 ľW when the structures were pumped by a 3-W multiline argon laser. These characteristics make the rib structures suitable as light sources for optical coherence tomography applications and facilitate their coupling to the optical fibre interferometers of such systems.
