An optical biosensor is provided for detecting a bio-molecular sample by Goos-Hänchen (GH) enhancement of Aharonov-Albert-Vaidman (AAV) amplification to a surface plasmon resonance (SPR) detector. The sensor includes pre- and post-selection polarizers respectively upstream and downstream of a right-isosceles prism with a metal film and a liquid medium disposed on a diagonal side of the prism. Laser light passes through the first polarizer, reflects at the film, passes through the second polarizer and is detected with a shift determined by a pointer estimator to indicate the sample.

Abstract:
An optical gyroscope is provided for measuring a small angular difference. The gyroscope includes a laser, a pre-selection polarizer, a first beam splitter, a coil of optical fiber, a second beam splitter, a post-selection polarizer, a spectrometer and an analyzer. The laser emits a pulse beam of coherent photons. The beam has pulse duration σ. The pre-selection polarizer pre-selects the photons, and the first beam splitter separates the photons by their horizontal |+ and vertical |− polarization eigenstates. These beams are launched into a fiber optical coil of radius r, which preserves polarization. The coil rotates by a difference rotation angle Δθ. The second beam splitter recombines the polarized photon beams as they exit the coil. The post-selection polarizer post-selects the photons. The spectrometer captures the post-selected photons and measures the associated frequency translation δω. The analyzer determines the difference rotation angle as Δ θ = ± ( c σ 2 tan χ 2 r ) δω , such that c is speed of light, and χ is post-selection polarization phase angle.
Abstract:
A magnetometer is provided for detecting a magnetic field of strength B using the Faraday effect. The magnetometer includes a photon emitter, a first polarizer, a prism, a second polarizer, a detector and an analyzer. The emitter projects an emitted light beam substantially parallel to the magnetic field and having wavelength λ. The prism has an interface surface and is composed of a Faraday medium having Verdet value V. The emitted light beam passes through the first polarizer and then the prism, exiting from the interface surface making an incident angle θ0 to normal of the surface and then refracting into a secondary medium as first and second circularly polarized light beams that are separated by a small angular divergence δ. These polarized light beams have average refraction angle θ to the normal and pass through a post-selection polarizer before the detector measures a weak value Aw of a photon having “which path” operator  associated with the polarized light beams. The magnetic field strength is determined as B ≈ - 2 ɛ A w π n 0 cos θ V λsin θ 0 . The parameters include n0 as index of refraction of the secondary medium, and ε as amplification factor. The pointer rotation angle Aw can be expressed as A w = ( θ + - θ - ) cos ɛ + [ ( θ + + θ - ) - 2 θ 0 ] sin ɛ 2 sin ɛ in which θ+ and θ− are respectively right- and left-polarized refraction angles with the average refraction angle such that θ = 1 2 ( θ + + θ - ) . The pointer rotation angle Aw can be approximated as Aw≈δ/2ε when 0
