Abstract: An electronically controllable apparatus is described which modulates a continuous wave laser beam 22 so as to produce an output beam 42 consisting of coherent "pulses" that are electronically controllable as to both pulse repetition rate and pulse width. The apparatus includes two acoustic devices 24, 26 positioned so that the laser beam passes through them in sequence, and apparatus 32 or 34 for passing sound waves through the devices to frequency shift the laser radiation as well as to diffract it. Each acoustic device such as 24 generates sound waves containing a group of frequencies which result in spaced pulses. The spreading of a laser beam at 40 which emanates from the first acoustic device 24 is countered by the second acoustic device 26 to produce a collimated, coherently pulsed, laser beam 42.

Abstract: The present invention relates to a light-transmissive element (106, 200, 500) which has light controlling properties. The light-transmissive element (106, 200, 500) comprises a plurality of first particles (206) and a plurality of second particles (208). The first particles (206) are configured to control the transmission of light of a first wavelength range being infrared light. The second particles (208) are configured to control the transmission of light of a second wavelength range being visible light. The first (206) and second particles (208) may independently be redistributed in an enclosure (207) enclosing the particles. Redistribution is enabled by an applied electric field which causes the particles to move in the enclosure (207). Thus, transmission of light of the first wavelength range and transmission of light of the second wavelength range is thereby independently controlled by the first (206) and second particles (208) respectively.

Abstract: An apparatus comprised of a cascaded series of optical modulators addressed by a multi-bit digital word with each optical modulator in the cascaded series being responsive to a single bit in the multi-bit digital word and wherein each of the optical modulators in the cascaded series of optical modulators doubling in effective optical length as a bit index of the bit of the multi-bit digital word to which it is responsive increases by a bit index value equal to one. The apparatus may be used with a prior art analog optical modulator and an associated ADC, having a fixed bit width, to extend the number of bits beyond the fixed bit width that the ADC and analog optical modulator prior art combination can otherwise operate.

Abstract: Apparatus and methods for forming a composite electrophoretic display comprised of multiple, stacked electrophoretic displays are described. The individual electrophoretic displays that form the composite display may be driven separately using different driving signals. The electrical connections for the individual displays may be configured to minimize the impact of the electrical connections on the overall aesthetic of the composite display.

Abstract: A system includes an optical parametric oscillator (OPO) device. The OPO device has an optical resonator, a first nonlinear optical element (NLO) and a second non-linear optical element (NLO). The first NLO can produce, via OPO of a first pump beam, a first output with a first frequency and a second output with a second frequency. The second frequency is lower than the first frequency. The second NLO can produce, via OPO of a second pump beam (with a higher frequency than the first), a third output with a third frequency and a fourth output with a fourth frequency. The fourth frequency is lower than the third frequency. The first frequency is the same, or at least substantially the same, as the fourth frequency. The OPO device is configured to resonate at the first frequency and the fourth frequency.

Abstract: A tunable PLC optical filter having sequentially connected thermally tunable Mach-Zehnder (MZ) interferometers is described. The cascade of MZ interferometers, each having a free spectral ranges matching ITU frequency grid spacing, are tuned so as to have a common passband centered on the frequency of the signal being selected, while having at least one of the stopbands centered on any other ITU frequency. Any other optical channel that may be present at any other ITU frequency is suppressed as a result. Another MZ interferometer in series with the cascade of interferometers including an asymmetric or variable coupler, is tuned to have low transmission at the center frequency of the selected optical channel.
