Integrated photonic interposers for processing octave-spanning microresonator frequency combs
Ashutosh Rao, Gregory Moille, Xiyuan Lu +7
Microcombs - optical frequency combs generated in microresonators - have advanced tremendously in the last decade, and are advantageous for applications in frequency metrology, nav…
On-chip polarization rotator for type I second harmonic generation
Eric J. Stanton, Lin Chang, Weiqiang Xie +12
We demonstrate a polarization rotator integrated at the output of a GaAs waveguide producing type I second harmonic generation (SHG). Form-birefringent phase matching between the p…
Hybrid Integrated Photonics Using Bulk Acoustic Resonators
Hao Tian, Junqiu Liu, Bin Dong +4
Microwave frequency acousto-optic modulation is realized by exciting high overtone bulk acoustic wave resonances (HBAR resonances) in the photonic stack. These confined mechanical…
PORT: A piezoelectric optical resonance tuner
Bin Dong, Hao Tian, Michael Zervas +2
This abstract presents an aluminum nitride (AlN) piezoelectric actuator for tuning optical resonance modes of silicon nitride photonic resonators. The AlN actuator is fabricated on…
Ultralow-power chip-based soliton microcombs for photonic integration
Junqiu Liu, Arslan S. Raja, Maxim Karpov +6
The generation of dissipative Kerr solitons in optical microresonators has provided a route to compact frequency combs of high repetition rate, which have already been employed for…
Double inverse nanotapers for efficient light coupling to integrated photonic devices
