103. Integrated, on-chip, semiconductor lasers at sub-micron wavelengths

Nima Nader (NIST)

ANZOS | Photonics and Optics (ANZCOP)

Invited talk

Development of stand-alone photonic integrated circuits (PICs) has been limited by lack of integration of active components such as lasers and amplifiers. Heterogeneous integration of group III-V quantum well (QW) or quantum dot active layers with passive PICs paves the way toward the generation, amplification, manipulation, and detection of coherent signals on a photonic chip. The demand from...

685. Chip-scale optomechanical magnetometers towards practical magnetic sensing

Contributed Oral

Magnetic-field sensors are important for applications including biomagnetic measurements, navigation, geophysical surveying, and communications in electromagnetically challenging environments. On-chip optomechanical magnetometers provide a route towards compact, room-temperature, deployable sensors by combining magnetically responsive mechanical elements with precise optical readout.

746. Hybrid Vaterite-Nanodiamond Probes for Combined Optical Trapping and Quantum Sensing

Mark Watson (The University of Qeensland; ARC Centre of Excellence in Quantum Biotechnology (QUBIC))

ANZOS | Photonics and Optics (ANZCOP)

Contributed Oral

Nitrogen-vacancy (NV) centre nanodiamonds are powerful biophysical probes that enable precise measurements of local environments through optical detection. The NV defect is accessible via optically detected magnetic resonance (ODMR), where shifts in the resonance frequencies are sensitive to temperature, strain, and electromagnetic fields. Achieving dynamic and accurate spatial control of...

135. Modelling and Analysis of Semiconductor Lasers Subject to Fibre Bragg Grating Feedback

Joe Steele (University Of Auckland)

ANZOS | Photonics and Optics (ANZCOP)

Contributed Oral

Semiconductor lasers are compact, efficient light sources widely used in optical communications, and their sensitivity to external feedback also makes them rich systems for studying nonlinear dynamics. The Lang–Kobayashi (LK) equations remain the standard framework for modelling feedback from a regular mirror, but many modern systems employ fibre Bragg gratings (FBGs) for their precise...

481. Frequency modulated photonic chip laser: suppression of residual amplitude modulation using integrated amplifier

Scott Bailey (Adelaide University)

ANZOS | Photonics and Optics (ANZCOP)

Contributed Oral

Photonic integrated lasers in the near infrared and visible offer narrow linewidths in a compact form factor, enabling portable quantum sensing technologies with performances that match traditionally lab bound systems. The application of these chip lasers requires careful design and operation considerations to meet the strict wavelength, power and modulation performance parameters, which can...
