We propose a novel technique for microlens fabrication which is compatible with silicon oxynitride technology, and enables the collimation of light exiting the waveguides into beams with divergence angles of 0.52°. Keywords-arrayed microlenses; integrated optics; waveguides
We designed an arrayed-waveguide grating spectrometer for the detection of early dental caries in teeth through polarized Raman spectroscopy. Measurement results on extracted human teeth demonstrate the feasibility of the approach. (Abstract) Keywords-component; Raman spectroscopy; integrated optics;
Solar photons possessing energy less than the bandgap of a single-junction solar cell can be utilized via upconversion (UC) two or more photons, resulting in emission single above-bandgap photon. Due to non-linear nature UC, highly concentrated light is required, which typically much greater practical concentration limits cell. It has been proposed that concentrating cells (UC-SC) with optical ...
Quantum technologies based on photons will likely require an integrated optics architecture for improved performance, miniaturization, and scalability. We demonstrate high-fidelity silica-on-silicon integrated optical realizations of key quantum photonic circuits, including two-photon quantum interference with a visibility of 94.8 +/- 0.5%; a controlled-NOT gate with an average logical basis fi...
Owing to the distinguishing properties of nondiffraction, self-healing, and transverse acceleration, Airy beams have attracted much attention in the past decade. To date, a simple approach for exquisitely fabricating cubic phase plates with both continuous variation of phase and micro size still remains challenging, which limits the generation of high-quality Airy beams for integrated micro-opt...
