Validation by 25km error free transmission of 10Gb/s directly modulated III-V/SOI hybrid DFB laser

Hyhrid III-V/SOI DFB lasers was designed and fabricated using wafer bonding; a low chirp parameter (α H ) of 2.4 was measured and 10Gb/s direct modulation demonstrated in an error-free transmission in a 25km single mode fiber.
