ANZOS | Photonics and Optics (ANZCOP)

Invited talk

Stimulated Brillouin scattering enables narrow-linewidth, GHz-centered photonic filtering, making it a key building block for integrated microwave photonics. Accessing radio-frequency bands beyond 15 GHz with SBS requires high frequency shifts and high gain coefficients, a combination that yet remains a challenge. Existing integrated platforms face a fundamental trade-off between Brillouin...

Brillouin microwave photonic (MWP) filters harness stimulated Brillouin scattering to frequency-selectively manipulate the amplitude of microwave signals in the optical domain, realising either a passband or notch response. A high-performance Brillouin MWP filter requires a low-phase-noise laser, high-bandwidth modulators, a high-gain Brillouin nonlinear medium, and high-bandwidth...

Optical parametric amplifiers/oscillators can produce squeezed light, which has reduced noise in one quadrature at the expense of increased noise in the other and shows promise in optical sensors and many quantum applications. However, highly squeezed light is difficult to measure due to contributions from a plethora of noise sources. In this talk, we quantify fundamental noise limits on...

Brillouin dynamic gratings (BDGs) provide a versatile mechanism for realizing reconfigurable narrowband optical filtering through optoacoustic interactions. While BDGs have been extensively studied in optical fibres, systematic investigations in integrated photonic platforms remain limited. Here, we demonstrate strong BDGs in low-loss heterogeneous As$_2$S$_3$–Ge:SiO$_2$ waveguides and...

105. Stimulated Brillouin Scattering in InGaP-on-SiO2 Waveguides

Contributed Oral

We present the simulation, fabrication, and experimental demonstration of on-chip stimulated Brillouin scattering (SBS) in InGaP-on-SiO₂ waveguides opera􀆟ng near 1550 nm. Brillouin scattering is a third-order nonlinear interaction between optical and acoustic waves that produces narrow linewidth microwave signals through the Brillouin gain process, desired for applications such as...
