摘要： An image processing apparatus having a third-order nonlinear stimulated photon echo medium (1). The photon echo medium (1) can store large numbers of images in the form of a Fourier transformed pattern by spectral modulation. The spectral modulation is carried out by sending optical pulses in an optical pulse train having (or not having) image information to the medium (1) so that the population in the ground and excited states are modulated after the passage of the pulse trains and pulses. The Fourier transformed pattern is converted back to temporal modulation, consisting of a sequence of echo pulses that reproduce the original data pulse train. By using the apparatus, ultrafast operation such as convolution and correlation between a number of reference images and a test image can be achieved.

摘要： A wafer scale implementation of an opto-electronic transceiver assembly process utilizes a silicon wafer as an optical reference plane and platform upon which all necessary optical and electronic components are simultaneously assembled for a plurality of separate transceiver modules. In particular, a silicon wafer is utilized as a “platform” (interposer) upon which all of the components for a multiple number of transceiver modules are mounted or integrated, with the top surface of the silicon interposer used as a reference plane for defining the optical signal path between separate optical components. Indeed, by using a single silicon wafer as the platform for a large number of separate transceiver modules, one is able to use a wafer scale assembly process, as well as optical alignment and testing of these modules.

摘要： Ferroelectric materials are disclosed as reversible holographic recording media (25) for use in two-photon recording systems. The ferroelectric materials disclosed herein provide long-lived electronic states intermediate the ferroelectric material's valence and conduction bands. These intermediate states have a sufficiently long life (on the order of 1 to 100 milliseconds) that low-power continuous wave ("cw") lasers (1) can be used to record interference patterns on them. Thus, two-photon holographic recording systems are also disclosed which do not require high-power, short pulse length, mode-locked or Q-switched lasers. The disclosed two-photon holographic recording systems provide for absorption of a first photon which excites electrons of holographic recording media to an intermediate state. Thereafter, upon absorption of a second photon, the electrons are promoted to the media's conduction band where they are arranged according to the interference pattern provided by the recording system. Importantly, the disclosed holographic recording systems employ visible and near IR cw lasers such as diode lasers.

摘要： An apparatus for transmitting optical signals includes an interposer for supporting opto-electronic components used to create optical output signals. An enclosure is used to encapsulate the populated interposer assembly and includes a silicon sidewall and a transparent lid. The sidewall is etched to include a turning mirror feature with a reflecting surface at a predetermined angle θ, the turning mirror disposed to intercept the optical output signals and re-direct them through the enclosure's transparent lid. A coverplate is disposed over and aligned with the enclosure, where the coverplate includes a silicon sidewall member that is etched to include a turning mirror element with a reflecting surface at the same angle θ as the enclosure's turning mirror element. The optical signals re-directed by the enclosure then pass through the transparent lid of the enclosure, impinge the turning mirror element of the coverplate, and are then re-directed along the longitudinal axis.

摘要： A method and apparatus for coherent time-domain optical data storage utilizing a randomizing phase modulation to increase storage capacity. A laser (10) generates write. read, and data pulses which are applied to an acousto-optic modulator (11), which modulates the pulses according to a modulation signal received from a radio-frequency modulator (12), and the modulated pulses are applied to the storage medium (13). The data signal to be recorded on the storage medium is subjected to spread-spectrum modulation, and in particular to pseudo-random phase modulation. The RF-modulator (12) modulates the write and read pulses with a frequency-chirping modulation and modulates the data pulse with the spread-spectrum modulated data signal before applying the respective pulses to the storage medium. The result is that a significantly longer data signal may be effectively recorded on the optical storage medium for a given characteristic de-phasing time of the medium.

摘要： An apparatus for providing self-aligned optical coupling between an opto-electronic substrate and a fiber array, where the substrate is enclosed by a transparent lid such that the associated optical signals enter and exit the arrangement through the transparent lid. The apparatus takes the form of a two-part connectorized fiber array assembly where the two pieces uniquely mate to form a self-aligned configuration. A first part, in the form of a plate, is attached to the transparent lid in the area where the optical signals pass through. The first plate includes a central opening with inwardly-tapering sidewalls surrounding its periphery. A second plate is also formed to include a central opening and has a lower protrusion with inwardly-tapering sidewalls that mate with the inwardly-tapering sidewalls of the first plate to form the self-aligned connectorized fiber array assembly. The fiber array is then attached to the second plate in a self-aligned fashion.
