Membrane hybrid optical devices and related technologies toward on-Si photonic integrated circuits

Toward realization of on-chip photonic integrated circuits on LSI for high performance computing, membrane III-V optical devices on Si using BCB bonding have been proposed. Strong optical confinement due to high index contrast between the core and cladding layers gives low threshold and high efficiency operation of lasers. Using a lateral current injection structure, RT-CW operation was demonstrated. The structure could be applied for other optical devices such as waveguide-type photodetectors and wire waveguides.
