We address here different features associated to the strength of the Bragg resonances, material imperfections and departure from the designed nominal values.","PeriodicalId":126085,"journal":{"name":"Proceedings of 2002 4th International Conference on Transparent Optical Networks (IEEE Cat.

Deep UV lithography, as used today in the CMOS industry, promises to deliver the accuracy together with the high volume capacity. In this paper, we will show photonic crystal-based structures fabricated with deep UV lithography. We will discuss the fabrication process, and how the differences of these structures with typical CMOS structures make the application of this technology anything but straightforward.","PeriodicalId":126085,"journal":{"name":"Proceedings of 2002 4th International Conference on Transparent Optical Networks (IEEE Cat.

Two types of devices have been studied: a commercial single-mode 50 mW laser emitting at 980 nm and the high-power laser grown by MBE at the Institute of Electron Technology emitting at 1010 nm. For both lasers the tuning range was close to 140 nm i.e. the 980 nm. laser can be tuned down to about 840 nm. Both the threshold currents and the quantum efficiencies remained constant throughout the whole tuning range. Pressure tuning might therefore be useful for diode-pumped solid-state lasers, which require pumping wavelengths in the 840-980 nm range.","PeriodicalId":126085,"journal":{"name":"Proceedings of 2002 4th International Conference on Transparent Optical Networks (IEEE Cat.

COST 268 \"Wavelength scale photonic components for telecommunications\" is an action in the COST Telecommunications domain. During the last four years this action has performed work and catalysed collaborations around the themes of vertical cavity devices, photonic bandgap structures and novel gain material devices. In this talk I will overview some of the work done in the action, showing examples of modeling tasks and characterisation results for wavelength scale photonic devices. With the Warsaw meeting likely also being the final meeting of the action, I will also try summarise and estimate what has been the impact of the action for the area of wavelength scale photonics. I will also discuss the special boundary conditions and collaboration formats of a COST action. Unlike, say the IST R&D project, a COST action has a more limited budget, but on the other hand it has a much broader collaboration format, in principle being open for all European states, new member states, as well as for external members, say from US or Japan. This means that the organisation of the work in a COST action should be done somewhat differently compared to a normal R&D project, and that there are things that cannot be done, as well as things that can be done better in this format. For instance, in COST 268 we have co-arranged a number of meetings, such as this one, as well as supported a number of short term inter-laboratory visits, typically used by younger researchers. At present the whole COST as a scientific organisation is being under evaluation, partly due to budget constraints. I will in the talk discuss on what have been the COST 268 experiences and argue why COST can be a very useful vehicle for scientific collaborations.","PeriodicalId":126085,"journal":{"name":"Proceedings of 2002 4th International Conference on Transparent Optical Networks (IEEE Cat.

Due to the asymmetric quantum-well heterostructures new possibilities to control spectral, power, and temporal properties of laser diodes and to widen their functionality are opened up.
