Abstract: The present disclosure relates to a cooking robot fry pan which comprises a pan body and a stirrer, wherein shaft bases are symmetrically arranged on the pan body; the shaft bases are composed of shaft sleeves and fixing sleeves; an exterior eave is arranged at one end of each shaft sleeve; bolt holes are uniformly distributed in the exterior eaves; the fixing sleeves are connected with the pan body; the shaft sleeves are positioned inside the fixing sleeves; the exterior eaves of the shaft sleeves are positioned at ports of the fixing sleeves; bolt holes are uniformly formed in the ports of the fixing sleeves; the exterior eaves of the shaft sleeves and the fixing sleeves penetrate through bolt holes in a one-to-one correspondence manner through bolts and are fixedly connected. Coaxiality of the shaft sleeves is ensured, and the stirrer stirrers smoothly.

Abstract: The present invention provides for a one or more layer graphene optical modulator. In a first exemplary embodiment the optical modulator includes an optical waveguide, a nanoscale oxide spacer adjacent to a working region of the waveguide, and a monolayer graphene sheet adjacent to the spacer. In a second exemplary embodiment, the optical modulator includes at least one pair of active media, where the pair includes an oxide spacer, a first monolayer graphene sheet adjacent to a first side of the spacer, and a second monolayer graphene sheet adjacent to a second side of the spacer, and at least one optical waveguide adjacent to the pair.

Abstract: An improved surface plasmon resonance (SPR) sensor is provided based on direct measurement of the Goos-Hänchen effect. Sensor sensitivity is enhanced by selecting the thickness of the metallic layer of the SPR sensor to be close to a critical thickness dcr where the effect of the surface plasmon resonance on the Goos-Hänchen shift is most pronounced. Overall sensor sensitivity is surprisingly found to improve with this approach, even though the measurement is based on a second order effect (i.e., the Goos-Hänchen shift) instead of the first order reflectance change measured in conventional SPR sensor approaches. The invention is also applicable to sensors based on measurements of other non-specular reflection parameters, such as temporal shifts, frequency shifts, and/or angular shifts.
