Additive GaN solid immersion lenses for enhanced photon extraction efficiency from diamond color centers
Xingrui Cheng, Nils Kolja Wessling, Saptarsi Ghosh +9
Effective light extraction from optically active solid-state spin centres inside high-index semiconductor host crystals is an important factor in integrating these pseudo-atomic ce…
Fabrication and transfer print based integration of free-standing GaN membrane micro-lenses onto semiconductor chips
Nils Kolja Wessling, Saptarsi Ghosh, Benoit Guilhabert +5
We demonstrate the back-end integration of broadband, high-NA GaN micro-lenses by micro-assembly onto non-native semiconductor substrates. We developed a highly parallel micro-fabr…
Photonic integration of lithium niobate micro-ring resonators onto silicon nitride waveguide chips by transfer-printing
Zhibo Li, Jack A. Smith, Mark Scullion +4
The heterogeneous integration of lithium niobate photonic waveguide devices onto a silicon nitride waveguide platform via a transfer-printing approach has been demonstrated for the…
A full degree-of-freedom photonic crystal spatial light modulator
Christopher L. Panuski, Ian R. Christen, Momchil Minkov +16
Harnessing the full complexity of optical fields requires complete control of all degrees-of-freedom within a region of space and time -- an open goal for present-day spatial light…
Ultra-high frame rate digital light projector using chipscale LED-on-CMOS technology
Navid Bani Hassan, Fahimeh Dehkhoda, Enyuan Xie +4
Digital light projector systems are crucial components in applications including computational imaging, fluorescence microscopy and highly parallel data communications. Here we pre…
Characterisation, Selection and Micro-Assembly of Nanowire Laser Systems
Dimitars Jevtics, John McPhillimy, Benoit Guilhabert +7
Semiconductor nanowire (NW) lasers are a promising technology for the realisation of coherent optical sources with extremely small footprint. To fully realize their potential as bu…
