摘要： Optical microcavities (12) based on two dimensional arrays of holes (14,18) defined in photonic crystals (10) are optimized for maximum Q factors and minimum mode volume. They can also be used for strong coupling between the cavity field and an atom trapped within a defect of the photonic crystals (10), or for tunable filters if the holes are filled with electro-optical polymers. In one embodiment the Q factor of a cavity is increased by elongation of a plurality of holes in at least one row in a predetermined direction. Modal structures of microcavities, as well as quality factors, mode volumes, symmetry properties and radiation patterns of localized defect modes as a function of the slab thickness and parameters of photonic crystal (10) and defects are illustrated.

摘要： The invention is directed to different methods for controlling the positions of the guided modes of the photonic crystal waveguides. Methods based on both rearrangement of the holes (12) and changing the size of the holes (12) are presented. We have observed and explained the appearance of acceptor-type modes and the donor-type waveguides. The ability to tune frequencies of the guided modes within a frequency bandgap is necessary in order to achieve efficient guiding of light within a waveguide (reduced lateral and vertical waveguide losses) as well as to match frequencies of eigen modes of different photonic crystal based devices in order to have good coupling between them.

摘要： A system, method and apparatus provide the ability to detect a chemical in an analyte. To detect the chemical, the invention utilizes a laser having an open cavity. A photonic crystal lattice structure having a defect defines a suitable geometry for such a cavity (1000). The analyte is introduced directly into a high optical field of the cavity (1002). Thereafter, the cavity is pumped (1004) and an emission from the laser is used to detect the presence of the chemical (1006) in the analyte.

摘要： Acoustic waves at microwave frequencies are workhorses for signal processing and emerging platforms for quantum information. Efficient and scalable controls of on-chip microwave phonons are, however, still missing and hinder the development of phononic integrated circuits. The present disclosure provides electrical control of on-chip traveling acoustic waves on a lithium niobate platform that operates at room and cryogenic temperatures. The elasticity is electrically tuned to demonstrate phase and amplitude modulators, and a serrodyne frequency shifter for gigahertz acoustic waves. Further, reconfigurable nonreciprocal acoustic phase modulation is provided by precisely engineering the phase matching between acoustic and quasi-traveling electric fields, reaching a nonreciprocity over 40 dB. This electro-acoustic platform comprises the fundamental elements for arbitrary acoustic signal processing and phononic quantum information.

摘要： A miniature optical biosensor and biosensor array where high sensitivity for detection of biomolecular interaction does not require a fluorescent label. Non-linear frequency- shifts of optical resonators ('nanobeams') provide a digital all-or-nothing response to equilibrium binding of a biomarker to surface-immobilized bio-recognition elements, a signal suitable to identify active components in genetic and proteomic circuits, as well as toxic substances. The threshold level for the digital response is adjustable to accommodate for varying receptor affinities. A bistable cavity sensing (BCS) method can be used to track the shift of the resonance induced by the analyte more precisely than the conventional cavity sensing method, where the resolution is limited by the cavity linewidth. BCS method can be used to quantitate the concentration of the analyte, and their binding kinetics, affinities and etc.
