Integration of laser diodes and photodiodes in photonic integrated circuit for measurement

Fully integrated PICs for measurement have been successfully fabricated for the first time. The device is implemented with waveguide grating components, a GRIN-SCH-SQW-DFB LD and PDs. Special care is taken to prevent direct optical coupling between integrated LDs and PDs in order to detect feeble se...

Zusammenfassung:	Fully integrated PICs for measurement have been successfully fabricated for the first time. The device is implemented with waveguide grating components, a GRIN-SCH-SQW-DFB LD and PDs. Special care is taken to prevent direct optical coupling between integrated LDs and PDs in order to detect feeble sensing light. An interference signal is actually detected as photocurrent modulation of ∼1-nA amplitude by this integrated structure.
