Autor: Field, James W., Berry, Sam A., Bannerman, Rex H. S., Smith, Devin H., Gawith, Corin B. E., Smith, Peter G. R., Gates, James C.

Publikováno v: Opt. Express 28, 21247-21259 (2020)

A blazed chirped Bragg grating in a planar silica waveguide device was used to create an integrated diffractive element for a spectrometer. The grating diffracts light from a waveguide and creates a wavelength dependent focus in a manner similar to a

Zn-indiffused diced ridge waveguides in MgO:PPLN generating 1 watt 780 nm SHG at 70% efficiency

Autor: Berry, Sam A., Carpenter, Lewis G., Gray, Alan C., Smith, Peter G. R., Gawith, Corin B. E.

Publikováno v: OSA Continuum 2, 3456-3464 (2019)

We present a metallic zinc indiffused diced ridge waveguide in magnesium doped periodically poled lithium niobate (MgO:PPLN) capable of generating over 1 W of 780 nm with 70% efficiency. Our 40 mm long waveguide has near circular fundamental mode out

High-birefringence direct UV-written waveguides for heralded single-photon sources at telecommunication wavelengths

Autor: Posner, Matthew T., Hiemstra, T., Mennea, Paolo L., Bannerman, Rex H. S., Hoff, Ulrich B., Eckstein, Andreas, Kolthammer, W. Steven, Walmsley, Ian A., Smith, Devin H., Gates, James C., Smith, Peter G. R.

Direct UV-written waveguides are fabricated in silica-on-silicon with birefringence of $(4.9 \pm 0.2) \times 10^{-4}$, much greater than previously reported in this platform. We show that these waveguides are suitable for the generation of heralded s

Modular Linear Optical Circuits

Autor: Mennea, Paolo L., Clements, William R., Smith, Devin H., Gates, James C., Metcalf, Benjamin J., Bannerman, Rex H. S., Burgwal, Roel, Renema, Jelmer J., Kolthammer, W. Steven, Walmsley, Ian A., Smith, Peter G. R.

We propose and demonstrate a modular architecture for reconfigurable on-chip linear-optical circuits. Each module contains 10 independent phase-controlled Mach-Zehnder interferometers; several such modules can be connected to each other to build larg

A two-way photonic interface for linking Sr+ transition at 422 nm to the telecommunications C-band

Autor: Wright, Thomas A., Francis-Jones, Robert J. A., Gawith, Corin B. E., Becker, Jonas N., Ledingham, Patrick M., Smith, Peter G. R., Nunn, Joshua, Mosley, Peter J., Brecht, Benjamin, Walmsley, Ian A.

Publikováno v: Phys. Rev. Applied 10, 044012 (2018)

We report a single-stage bi-directional interface capable of linking Sr+ trapped ion qubits in a long-distance quantum network. Our interface converts photons between the Sr+ emission wavelength at 422 nm and the telecoms C-band to enable low-loss tr
