A micro-optical module for multi-wavelength addressing of trapped ions
M. L. Day, K. Choonee, Z. Chaboyer +4
The control of large-scale quantum information processors based on arrays of trapped ions requires a means to route and focus multiple laser beams to each of many trapping sites in…
60dB high-extinction auto-configured Mach--Zehnder interferometer
Callum M. Wilkes, Xiaogang Qiang, Jianwei Wang +7
Imperfections in integrated photonics manufacturing have a detrimental effect on the maximal achievable visibility in interferometric architectures. These limits have profound impl…
Point-by-point inscription of apodized fiber Bragg gratings
Robert J. Williams, Christian Voigtländer, Graham D. Marshall +4
We demonstrate apodized fiber Bragg gratings inscribed with a point-by-point technique. We tailor the grating phase and coupling amplitude through precise control over the longitud…
Cladding mode coupling in highly localized fiber Bragg gratings: modal properties and transmission spectra
Jens Thomas, Nemanja Jovanovic, Ria G. Becker +5
The spectral characteristics of a fiber Bragg grating (FBG) with a transversely inhomogeneous refractive index profile, differs con- siderably from that of a transversely uniform o…
Three-dimensional imaging of direct-written photonic structures
Graham D. Marshall, Alexander Jesacher, Anisha Thayil +2
Third harmonic generation microscopy has been used to analyze the morphology of photonic structures created using the femtosecond laser direct-write technique. Three dimensional wa…
A 100 mW monolithic Yb waveguide laser fabricated using the femtosecond laser direct-write technique
Martin Ams, Peter Dekker, Graham D. Marshall +1
A femtosecond laser-written monolithic waveguide laser (WGL) oscillator based on a distributed feedback (DFB) architecture and fabricated in ytterbium doped phosphate glass is repo…
