6 THz range tunable 2.5 Gb/s frequency conversion by a multiquantum well Y laser

Autor: Klaus Wunstel, K. Dutting, O. Hildebrand, Gert Laube, D. Baums, Wilfried Idler, Michael Schilling

Publikováno v: IEEE Journal of Quantum Electronics. 29:1835-1843

Improved monolithic interferometric semiconductor lasers in Y configuration are reported. When they are operated as electrically tunable light sources, single-longitudinal-mode emission with a very large CW tuning range up to 51 nm is obtained. By us

Selective MOVPE of semi-insulating InP layers for high speed OEICs

Autor: A. Nowitzki, Gert Laube, P. Speier, K. Dutting

Publikováno v: Journal of Crystal Growth. 107:156-160

MOVPE growth on patterned substrates and doping behaviour of iron in InP were studied at different reactor pressures. The key parameters for a successful control of selective MOVPE like the growth temperature, growth rate, reactor pressure and the ra

10 Gb/s wavelength conversion with integrated multiquantum-well-based 3-port Mach-Zehnder interferometer

Autor: Gert Laube, E. Lach, K. Dutting, P. Wiedemann, K. Daub, Klaus Wunstel, Wilfried Idler, Michael Schilling, M. Klenk

Publikováno v: IEEE Photonics Technology Letters. 8:1163-1165

All-optical wavelength conversion of 10 Gb/s data with simultaneous regeneration of the extinction ratio is achieved by means of a monolithic 3-port Mach-Zehnder interferometer. The reported devices are based on an all active multiquantum-well wavegu
