An InGaAlAs short-cavity DBR laser enabling 1.3-μm, uncooled, 10-Gbit/s operation at lower drive currents is demonstrated. This laser consists of a short InGaAlAs-MQW active region butt-jointed to an InGaAsP-DBR region. This structure provides moderate chip power, low threshold current, and a large relaxation oscillation frequency simultaneously, because it has an optimum cavity length in the range between 10 and 100 μm, at which both VCSELs and conventional edge-emitters cannot be formed because of their difficulty of manufacture. The fabricated 75-μm short-cavity laser demonstrated 100°C, 10-Gb/s operation at a record low drive current of 14 mAp-p. Furthermore, it achieved side-mode suppression ratio of more than 37 dB at a high yield of 95%, because of the naturally high single-mode stability of its short-cavity DBR structure.
