A method of operating an avalanche photodiode includes providing an avalanche photodiode having a multiplication region capable of amplifying an electric current when subject to an electric field. The multiplication region, in operation, has a first ionization rate for electrons and a second, different, ionization rate for holes. The method also includes applying the electric field to the multiplication region, receiving a current output from the multiplication region, and varying the electric field in time, whereby a portion of the current output is suppressed.

A nanocomposite optical-element comprising a first surface, a second surface, and a nanocomposite between the first and the second surface. The nanocomposite comprising of a plurality of refractive-gradients, the plurality of refractive-gradients comprising one or more nanofillers dispersed in a cured organic-matrix. The nanofillers concentration variation determining the plurality of refractive-gradient profiles such that a profile discontinuity exists between any of the plurality of refractive-gradients that are adjacent.

An apparatus for manufacturing nanocomposite-ink, the apparatus comprising, a nanoparticle reservoir, an organic-matrix reservoir, a homogenizer, and a dispenser. The homogenizer combines the nanoparticles and the organic-matrix, dispersing the nanoparticles within the organic-matrix, thereby producing a nanocomposite-ink for dispensement by the dispenser.

An imaging device comprises of a pixelated array of semiconductor detector elements, in which each detecting element is electrically connected to an integrated circuit, the integrated circuit of each of the pixels comprising a passive signal path and a transient signal path. The passive path provides consecutive frame or scene imaging and the transient path detects the transient electromagnetic events such as laser pulses. The transient path is electrically connected to a timing circuit, the timing circuit for determining the time-of-flight of return pulses emitted from the electromagnetic source detected by the transient signal paths. Wherein the passive path and transient path operate simultaneously enabling simultaneous passive and LADAR imaging.
