For ease of clear optics working storage principle of work of the present invention, respectively the principle of work of each element described in the various embodiments described above is described in detail here.
Single wavelength single longitudinal mode polarization laser: as light source, be 1 when light intensity is arranged, be 0 during no light intensity, have the switching rate of light between unglazed to be the dominant frequency of this element.
Optical input element and light output element: in the traditional optical design, the input and output of signal can directly be realized by the transmission of same laser instrument aplanatism beam splitting by light.And in the micronano optical design, the input and output of signal can be realized by the transmission of polarization fiber or waveguide.
Light beam splitting element and combiner element: in traditional optical, can realize by semi-transparent semi-reflecting mainly that namely the optical glass of a slice plated film is divided into two bundles with incident light in transmission and reflection direction; Perhaps the light of two bundles with 90 degree angle incidents is lumped together in transmission and reflection direction.And in the design of fiber optics and micronano optical, the beam splitting of light beam and close bundle and can realize by controlling the transmission mode (bifurcated or crossing) of two-way light in waveguide (light path of optical fiber or etching).The present invention is mainly by etching SiO on silicon chip
2The light beam splitting groove of the light path that the mode of film realizes and combiner groove, wherein " groove " technology can use little processing mode such as electron beam exposure or ion beam etching to realize.
Need to prove in addition: light beam splitting groove is that a branch of light is divided into two bundles, and the phase information of two-beam is constant, and amplitude is original 1/2.The combiner groove is mainly used in realizing computing function, namely realizes the coherence stack of two-beam.Because the fluctuation transport property of light, its phase place is to change in the cycle with the wavelength on working direction, if when the optical path difference of two light waves be λ/2 odd-multiple apart from the time, the phase place of two light waves is opposite fully, if amplitude (being assumed to be 1) is identical again, disappear mutually because its undulatory property is interfered, two light waves close the light intensity that shows behind the bundle and are 0; If the two-beam optical path difference is the integral multiple of λ, the phase place of two light waves is identical, the relevant enhancing then occur, and amplitude is 2.Shown in following table 1 and table 2, wherein symbol " ↑ " and " ↓ " are used for the expression phase place.

2The silicon chip of film forms circular micro-cavity structure or inlays the nanometer metal structure with surface plasma function at silicon chip and realize.Circular micro-cavity structure is strapped in the light of certain pattern within the microcavity, when controlling light and enter this system, causes the kinetic property (as vibrating mode etc.) of structure that small sample perturbations takes place, and influence the state of chamber film, thereby picked up signal is exported.In this process, microcavity is in excited state (standard signal supply) all the time, and outside stimulus (control end) changes its chamber mould to reach moment coupling output (result after the integer).The similar miniature pulsed laser of its operational mode, the population number is in the excited state of counter-rotating but does not have suitable pattern output, make its pattern moment reach coupling condition up to outside stimulus occurring, exported a pulse, enter next the circulation after energy discharges naturally.In general, such micro-cavity structure is if annulus then can pass through SiO
