Abstract :
We show the aspects that rule the design of a Hybrid Distributed Bragg Reflector (HDBR) package and a possible low cost solution with adhesives. We ensure single-mode behaviour in a operative range of 10°C (17-27°C) bending and fixing a tapered fiber to a very stable ceramic structure. The source at 1.55 μm, suitable for direct modulation at 2.5 Gbit/s, exhibits a temperature dependence of 0.013 nm/°C (nearly one order of magnitude less than a typical DFB laser) and a static linewidth lower than 40 kHz at 1.5 mW output power, with Side Mode Suppression Ratio (SMSR) of 43 dB
