Abstract

The demand for high-speed data communications has lead to techniques for reducing the cost of laser sources with high quality spectral performance. The etching of a short 2D-lattice of holes adjacent to the ridge waveguide of a Fabry-Perot laser can be used to create a single-contact, single-mode device,^1,2 without the expensive regrowth needed for DFB and DBR lasers. Forthcoming transceiver designs³ will place stringent demands on the modulation capabilities of sources. The challenge here is to design a source, which possesses sufficient bandwidth for the desired data rate. Considerable work has previously been carried out on gain-lever lasers,^4–5 which show enhanced modulation efficiency. In this paper we present a two-contact device with an increased small signal bandwidth and by incorporating the ID-tattke grating, tingle-mode performance is demonstrated. Moreover, the two-contact device scheme facilitates a new regime for low drive current operation at 10Gb/s
