Dual laser self-injection locking to a micro Fabry–Perot for low phase noise millimeter-wave generation

open access: yesAPL Photonics
Low-noise and accessible millimeter-wave sources are critical for emergent telecommunications, radar, and sensing applications. Current limitations to realizing low-noise, deployable millimeter-wave systems include size, weight, and power requirements ...

Optical computing by injection-locked lasers

open access: yes, 2017
A programmable optical computer has remained an elusive concept. To construct a practical computing primitive equivalent to an electronic Boolean logic, one should find a nonlinear phenomenon that overcomes weaknesses present in many optical processing ...

Self-injection-locked optical parametric oscillator based on microcombs

open access: yesOptica
Narrow-linewidth yet tunable laser oscillators are one of the most important tools for precision metrology, optical atomic clocks, sensing, and quantum computing. Commonly used tunable coherent oscillators are based on stimulated emission or stimulated Brillouin scattering; as a result, the operating wavelength band is limited by

4H-SiC microring opto-mechanical oscillator with a self-injection locked pump

open access: yesAPL Photonics
We have demonstrated, for the first time to our knowledge, self-injection locking of a distributed feedback diode laser to a multimode 4H-silicon carbide (4H-SiC) microring resonator, which is also used for the observation of resonant opto-mechanical ...

A wearable self-aid microneedle chip based on actively transdermal delivery of epinephrine

open access: yesMicrosystems & Nanoengineering
Epinephrine is important for first aid and usually applied via injection, which is painful and problematic in operation, thereby making it difficult to self-delivery.
