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 Å at 1.2 times threshold current.
