Polarisation effects in optical microresonators [PDF]

2015 IEEE Photonics Conference (IPC), 2015
Polarization effects in different types of optical microresonators are studied in detail. It is observed that microresonators with tighter axial power confinement, such as MBRs and micro-milled resonators, show larger cross-polarization coupling efficiencies.

Flexible Tuning Optical Frequency Combs via Parametric Seeding in Microresonators With Normal Dispersion

IEEE Photonics Journal, 2015
We propose a novel method to flexibly tune the optical frequency combs generated in normal-dispersion microresonators based on parametric seeding. The pulse duration could be adjusted in the range of 0.7-3.076 ps by changing the seeding power from 1 to 5

Fabrication of a microresonator-fiber assembly maintaining a high-quality factor by CO2 laser welding

, 2015
We demonstrate fabrication of a microtoroid resonator of a high-quality (high-Q) factor using femtosecond laser three-dimensional (3D) micromachining. A fiber taper is reliably assembled to the microtoroid using CO2 laser welding.

Germanium‐Based Mid‐Infrared Integrated Photonics

Laser &Photonics Reviews, EarlyView.
The mid‐infrared (mid‐IR) spectral range is a part of the electromagnetic spectrum in which most of the molecules have vibrational and rotational resonances. Photonics integration in this wavelength range have thus seen a burst of interest in the recent years, mainly driven by applications related with the detection of chemical and biological ...

Octave‐Spanning, Deterministic Single Soliton Generation in 4H‐Silicon Carbide‐On‐Insulator Microring Resonators

Laser &Photonics Reviews, EarlyView.
The miniaturization of metrology and precision spectroscopy systems requires robust, turn‐key microcombs with broad bandwidth, low threshold, and high efficiency. Here, high‐Q, dispersion‐engineered microresonators in a high‐confinement nonlinear SiC platform, combined with waveguide‐enabled thermal management and laser cooling, enable deterministic ...

Broadband Parametric Amplification in AlGaAs‐on‐Insulator Nanowaveguides

Laser &Photonics Reviews, EarlyView.
Harnessing the exceptional nonlinearity of AlGaAs‐on‐insulator nanowaveguides, four‐wave‐mixing parametric amplification achieves a record net on‐chip gain of 56 dB and a gain bandwidth exceeding 415 nm at telecom wavelengths. These results establish AlGaAsOI as a powerful platform for compact, high‐performance integrated nonlinear optical ...
