Brillouin comb line amplifiers for optical atomic clocks
Ryan L. Russell, Lachlan Pointon, Sarah Katherine Scholten +10
Optical atomic clocks outperform the microwave clocks at the heart of current timing and navigation infrastructure by orders-of-magnitude, and recent progress in on-chip integratio…
Stimulated Brillouin Scattering in InGaP-on-Insulator Waveguides
Yuyang Xue, Lisa-Sophie Haerteis, Ryan L. Russell +8
Stimulated Brillouin Scattering (SBS) is a nonlinear interaction between optical and acoustic waves in solids. First regarded as a parasitic process in optical fibers, it has gathe…
Brillouin-Enhanced Photonic Stepped-Frequency Radar
Ziqian Zhang, Ryan L. Russell, Choon Kong Lai +1
Photonic stepped-frequency (SF) radar offers high range resolution and only requires low-speed driving electronics, but existing architectures face challenges in achieving low phas…
Brillouin lasers in Bragg grating microresonators
Ryan L. Russell, Moritz Merklein, Choon Kong Lai +5
Chip-scale coherent light sources are required in applications spanning metrology and sensing to telecommunications. Brillouin lasers (BLs) offer a route to ultra-coherent optical…
