Embodiment Construction

[0037] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0038] It should be noted that if there is a directional indication (such as up, down, left, right, front, back...) in the embodiment of the present invention, the directional indication is only used to explain that it is in a specific posture (as shown in the drawings). If the specific posture changes, the relative positional relationship, movement, etc. of the components below will also change the directional indication accordingly.

Abstract

The invention discloses an optical logic device with multibit input of a micro-cavity structure and a method, and relates to the technical field of photon chips. The optical logic device comprises a metal substrate, a metal-intermediate-metal waveguide, and a plurality of micro-ring resonators. The metal substrate has an upper surface. The metal-intermediate-metal waveguide is etched on the uppersurface. The micro-ring resonators are etched on the two sides of the metal-intermediate-metal waveguide respectively. The metal-intermediate-metal waveguide and the micro-ring resonators have the same height, and the highest position is higher than or is flush with the surface of the metal substrate. By means of the coupling structure of the micro-ring resonators and the metal-intermediate-metal(MIM) waveguide, SPPs wave guiding can be perfectly supported, the high coupling resonance effect is achieved, and the optical logic device is suitable for high-performance optical logic treatment; with the micro-ring resonators as input ports, multibit signal input control can be realized only by increasing the number of the micro-ring resonators; the optical logic device has high sensitivity tothe refractive index of the resonators, great contrast is realized in the height states of output ports, and the logic operation bit error rate is reduced.

Description

Technical field [0001] The invention relates to the technical field of photonic chips, in particular to an optical logic device and method for multi-bit input with a microcavity structure. Background technique [0002] Compared with traditional electronic integrated circuits, Photonic Integrated Circuit (PIC) has the advantages of more functions, strong interference capability, no temperature drift, faster transmission speed, and no quantum effect limitation. It is expected to become the next generation of high-speed computers. The main components of the original. In recent years, large-scale PIC devices integrating both active and passive devices have been manufactured. In the past research, a variety of basic optical circuit devices that have been studied and mature have been proposed, such as optical switches based on planar waveguides, optical filters, optical modulators, optical multiplexers / demultiplexers, lasers, various optical detectors, etc. . However, nowadays, all-...
