Multiwavelength Membrane Laser Array on Si Using Selective-area Epitaxial Growth

We have developed a selective-area epitaxial growth technique using InP template directly bonded on SiO
2
/Si substrate, and obtained multiple MQWs with different photoluminescence peak wavelengths by a single growth process. We successfully demonstrated the high-speed direct modulation with an 8-ch WDM membrane laser array.
