Claim Text:
1. A method of integrating all active and passive optical devices on a silicon (Si)-based integrated circuit (IC), comprising steps of: (a1) providing a Si substrate; obtaining at least one electronic device on said Si substrate; and obtaining a first insulating layer to be covered on said Si substrate and said at least one electronic device; (b1) pattern-etching said first insulating layer to form a first groove on said Si substrate; obtaining an active-layer semiconductor in said first groove and on said first insulating layer; and obtaining a second insulating layer to be covered on said active-layer semiconductor; (c1) by using rapid melt epitaxy (RMG), said active-layer semiconductor comprising a filling part and a waveguide part after an annealing process to obtain a layer of a material selected from a group consisting of a single crystal and an alloy on said Si substrate and said at least one electronic device, said filling part being located in said first groove, said waveguide part being located on said first insulating layer and perpendicularly connected with said filling part; and obtaining an optical emitter and an optical receiver; and (d1) obtaining a third insulating layer to be covered on said optical emitter, said optical receiver, said waveguide part and said first insulating layer; after pattern-etching, obtaining a plurality of second grooves on said at least one electronic device, said optical emitter and said optical receiver; through said second grooves, obtaining a plurality of metal pads on said at least one electronic device, said optical emitter and said optical receiver to input and output electronic signals.
