A new device in the hybrid III-V on Silicon-On-Insulator (SOI) toolbox is proposed for all-optical signal processing applications. The membrane InP switch (MIPS) consists of a bonded III-V membrane waveguide of only 100 nm thick which is coupled to the
underlying SOI circuit. Because of the high index contrast between the III-V membrane and the surrounding cladding, a high confinement of light is achieved in the active region of the device, leading to compact devices that can be optically pumped with a
strong light-matter interaction. Operation as an optical amplifier, all-optical switch and passive regenerator is demonstrated.
