| Abstract: | Low-threshold-current and high-power operation of 1.5 ?m GaInAsP/InP bundle-integrated-guide (BIG) DBR lasers were obtained. A single-mode operation temperature range of more than 70 deg was demonstrated around room temperature by shortening the active region to 100 ?m. The modulation characteristic was measured up to 2 GHz with a modulation depth of 100%. A maximum value of dynamic wavelength shift was 2 ? at 1.2 times threshold current. |
