基金For the development of the generic PIC platform outlined in the article funding has been received from the European Commission through the projects EuroPIC(www.europic.jeppix.eu)PARADIGM(www.paradigm.jeppix.eu),and InPulse(www.inpulse.jeppix.eu).The 4-array EML chips(refer to Fig.7)was developed in the framework of the PIANO+-ALOHA project(grant#01BP1125).The other topics have been conducted on HHI internal funding.
