Abstract: In accordance with a method for individually addressing qubits in a set of qubits, a plurality of qubits is provided that each have two internal states representing a unit of quantum information. A transition between the two internal states of each qubit is caused by a two-photon Raman transition. Each of N ones of the qubits in the plurality of qubits are individually addressed using one of N pairs of laser beams, respectively, N being an integer greater than or equal to two. The laser beams in each of the N pairs have a frequency difference equal to a qubit transition frequency that represents a difference in frequency between the two internal states of the qubits. The laser beams in each pair of laser beams operate at different frequencies than the laser beams in every other pair of laser beams.

Abstract: Methods and systems providing laser outputs are disclosed. A first laser input from a first pump laser source has a first average power, and a second laser input from a second pump laser source has a second average power. A first laser output is generated based on conversion of the first laser input and the second laser input at the first state. After generating the first laser output, the second laser input is provided at a second state with the second average power remaining unchanged. After generating the first laser output, a second laser output is generated based on conversion of the first laser input and the second laser input at the second state. Combined powers of the first laser input and the second laser input remain the same when generating the first and second laser outputs, but powers of the first and second laser outputs are different.

Abstract: Provided are an electro-optical device, a laser device, and an electro-optical dual-comb generator. The electro-optical device includes a waveguide configured to generate a dispersive wave of which a center wavelength is different from a center wavelength of the incident wave of the waveguide, and a wavelength modulator disposed along the waveguide and configured to absorb the incident wave propagating through the waveguide, wherein, as the wavelength modulator absorbs the incident wave, the center wavelength of the dispersive wave changes.

Abstract: An optical source (100) comprising a supercontinuum generation apparatus comprising a pump light source (102), a twisted photonic crystal fibre, PCF, (104) and a wideband quarter-wave retarder (106). The pump light source is arranged to provide circularly polarised pump light. The twisted PCF is arranged to receive the pump light and to convert the pump light into circularly polarised supercontinuum light. The wideband quarter-wave retarder is arranged to convert the circularly polarised supercontinuum light into linearly polarised supercontinuum light. The optical source may additionally comprise a wavelength tunable bandpass optical filter arranged to transmit the linearly polarised supercontinuum light at wavelengths within a selected range.

Abstract: A phonon-mediated upconversion method includes exciting a Raman phonon in a crystal by illuminating the crystal with a number of pump beams each having a same pump frequency equal to one half of a phonon frequency of the Raman phonon. The method also includes generating an upconverted beam by illuminating the crystal with at least one of the number of pump beams while the Raman phonon is at least partially excited. The upconverted beam has an upconverted frequency that is three times the pump frequency.

Abstract: An integral optical resonant cavity for frequency conversion is provided. The integral optical resonant cavity includes: a housing, a cavity-length adjustment device, a temperature control device and a nonlinear crystal provided in the temperature control device; a first plano-concave mirror and a second plano-concave mirror included in the cavity-length adjustment device and a nonlinear crystal form the optical resonant cavity; and light passes through the first plano-concave mirror, the nonlinear crystal and the second plano-concave mirror sequentially. The stability of the length of the optical resonant cavity is improved through an integral design thereof, and the stability of the temperature of the nonlinear crystal in the integral optical resonant cavity is improved through the temperature control device, thereby stably controlling relative phases between light fields for the frequency conversion in the resonant cavity. Meanwhile, the length of the integral optical resonant cavity is accurately controlled through the cavity-length adjustment device.

Abstract: An assembly comprises a space configured for placing a medium to receive a first radiation for generating a second radiation. In operation, the second radiation propagates coaxially with the first radiation after the medium. The assembly further comprises an optical element after the medium for transmitting or reflecting the first radiation with a surface area. The assembly is configured such that, in operation, a cleaning gas is in contact with the surface area. A reactive medium is generated from at least a part of the cleaning gas by the second radiation for removing a contamination from the surface area.

Abstract: The present disclosure relates to active cancellation of frequency noise in lasers. One example embodiment includes a device. The device includes an optical cavity exhibiting a resonant optical frequency. The device also includes a laser. An output of the laser is locked to the resonant optical frequency. A first portion of the laser output is transmitted through the optical cavity to filter out high-frequency noise from the first portion of the laser output to generate a modified signal. Additionally, the device includes an acousto-optic modulator configured to generate a reference signal. Further, the device includes a feedforward circuit configured to receive a first portion of the reference signal and generate a feedforward signal. In addition, the device includes an electro-optic modulator configured to interfere a second portion of the reference signal with a second portion of the modified signal using the feedforward signal to generate an output signal.

Abstract: An optical component serves as a nonlinear photodetector for generating a nonlinear electrical signal. The component comprises a first electrically conductive layer, a second electrically conductive layer and an absorption layer. The absorption layer is arranged between the first and the second electrically conductive layer and has a layer thickness of at least 500 nm. The electrical signal is generated by the component by applying a voltage at the component and irradiating the component with electromagnetic radiation in a first wavelength range (λ1) with a radiation intensity of less than 10 nW/mm2 and also irradiating the optical component with electromagnetic radiation in a second wavelength range (λ2) that is different from the first wavelength range (λ1) and a radiation intensity of less than 100 nW/mm2.
