On-chip all-optical switching network apparatus, semiconductor device, and method for manufacturing the same

An on-chip all-optical switching network apparatus, comprising:

• a photonic chip in which at least two photonic integrated circuit (PIC) sub-chips are formed, wherein adjacent photonic integrated circuit sub-chips are optically interconnected with each other;
• and
• at least two optical switching control analog electrical chips respectively disposed on the at least two photonic integrated circuit sub-chips;
• wherein each photonic integrated circuit sub-chip comprises at least one on-chip optical switch, at least two communication nodes configured to communicate with external devices, and a plurality of first-type optical waveguides configured to connect the at least one on-chip optical switch with the communication nodes, wherein each on-chip optical switch is arranged in a one-to-one correspondence with a respective one of the at least two optical switching control analog electrical chips;
• and
• wherein, on the photonic chip, any two of the communication nodes are configured to communicate with each other via the at least one on-chip optical switch.
