Low power, chip-based stimulated Brillouin scattering microwave photonic filter with ultrahigh selectivity
David Marpaung, Blair Morrison, Mattia Pagani +5
Highly selective and reconfigurable microwave filters are of great importance in radio-frequency signal processing. Microwave photonic (MWP) filters are of particular interest, as…
Phase-locking in Multi-Frequency Brillouin Oscillator via Four Wave Mixing
Thomas F. S. Buettner, Irina V. Kabakova, Darren D. Hudson +4
Stimulated Brillouin scattering (SBS) and Kerr-nonlinear four wave-mixing (FWM) are among the most important and widely studied nonlinear effects in optical fibres. At high powers…
Si3N4 ring resonator-based microwave photonic notch filter with an ultrahigh peak rejection
David Marpaung, Blair Morrison, Ravi Pant +5
We report a simple technique in microwave photonic (MWP) signal processing that allows the use of an optical filter with a shallow notch to exhibit a microwave notch filter with an…
Frequency agile microwave photonic notch filter with anomalously-high stopband rejection
David Marpaung, Blair Morrison, Ravi Pant +1
We report a novel class microwave photonic (MWP) notch filter with a very narrow isolation bandwidth (10 MHz), an ultrahigh stopband rejection (> 60 dB), a wide frequency tuning (1…
Acoustic confinement and Stimulated Brillouin Scattering in integrated optical waveguides
Christopher G. Poulton, Ravi Pant, Benjamin J. Eggleton
We examine the effect of acoustic mode confinement on Stimulated Brillouin Scattering in optical waveguides that consist of a guiding core embedded in a solid substrate. We find th…
Narrow linewidth Brillouin laser based on chalcogenide photonic chip
Irina V. Kabakova, Ravi Pant, Duk-Yong Choi +4
We present the first demonstration of a narrow linewidth, waveguide-based Brillouin laser which is enabled by large Brillouin gain of a chalcogenide chip. The waveguides are equipp…
