Enhanced sensitivity of silicon-photonics-based ultrasound detection via BCB coating
Resmi Ravi Kumar, Evgeny Hahamovich, Shai Tsesses +3
Ultrasound detection via silicon waveguides relies on the ability of acoustic waves to modulate the effective refractive index of the guided modes. However, the low photo-elastic r…
