(author) Static and dynamic performance optimization of a 1.3 µm GaInNAs ridge waveguide laser 2008 In: 2008 International Conference on Numerical Simulation of Optoelectronic Devices, NUSOD'08; Nottingham; United Kingdom; 1 September 2008 through 4 September 2008. - 9781424423071 ; , s. 121-122 Conference paper (peer-reviewed)abstract In this work, we optimise the structure of an uncooled directly modulated 1.3 μm GaInNAs ridge waveguide laser for high temperature operation. The static and dynamic performance of the optimised design is analyzed using an accurate in-house 2D electro-opto-thermal laser simulator. The optimised structure Is shown to have a lower threshold current, higher efficiency, higher modulation bandwidth and lower vertical beam divergence compared to a reference structure with a conventional design. Large-signal 10 Gbit/s digital modulation simulations were performed and demonstrate the improved performance of the optimised structure especially under high temperature operation.

234.	Lim, Jun, et al. (author) Static and dynamic performance optimisation of a 1.3 mu m GaInNAs ridge waveguide laser 2008 In: Optical and Quantum Electronics. - : Springer Science and Business Media LLC. - 0306-8919 .- 1572-817X. ; 40:14-15, s. 1181-1186 Journal article (peer-reviewed)abstract In this work, we perform a multi-parameter design study to improve the performance of an uncooled directly modulated 1.3 mu m GaInNAs ridge waveguide laser for high speed operation especially at high temperature. The static and dynamic performance of the improved design is analyzed using an accurate in-house 2D electro-opto-thermal laser simulator. The improved structure is shown to have a lower threshold current, higher thermal roll-over limit and higher modulation bandwidth-especially under high temperature operation. The improved structure also has a lower vertical beam divergence compared to a reference structure with a conventional design.

238.	Lindberg, Hans, 1977, et al. (author) High-power optically pumped 1550-nm VECSEL with a bonded silicon heat spreader 2004 In: IEEE Photonics Technology Letters. - 1041-1135 .- 1941-0174. ; 16:5, s. 1233-1235 Journal article (peer-reviewed)abstract We present an optically pumped 1550-nm vertical-external-cavity surface-emitting laser with improved output power and operating temperature using a bonded heat spreader. The laser comprises an InGaAsP-based gain element, with a resonant periodic gain structure on top of a distributed Bragg reflector, and a high reflectivity spherical mirror as the external reflector. Heat transport is enhanced by a Si heat spreader bonded to the InGaAsP surface by liquid capillary bonding. Optical pumping is achieved using a 1250-nm fiber Raman laser. A maximum continuous output power of 250 mW was obtained under multitransverse mode operation at 240 K. Under operation in the fundamental near-Gaussian mode, we obtained a maximum power of 230 mW with a beam quality factor (M-2) of 1.22. At room temperature, the output power was limited to 12 mW.

240.	Lindberg, Hans, 1977, et al. (author) InP-based optically pumped VECSEL operating CW at 1550 nm 2004 In: IEEE Photonics Technology Letters. - 1041-1135 .- 1941-0174. ; 16:2, s. 362-364 Journal article (peer-reviewed)abstract We present a vertical external-cavity surface-emitting laser operating at 1550 run. The laser comprises an InGaAsP-based gain element, with a resonant periodic gain structure on top of a distributed Bragg reflector, and a high reflectivity spherical mirror as the external reflector. Optical pumping is achieved using a 1250-nm fiber Raman laser. A maximum continuous output power of 70 mW was obtained under multitransverse mode operation at 233 K. Under single-mode operation, we obtained a maximum power of 60 mW with a beam quality factor M-2 less than 1.1.
