Heterogeneously Integrated Balanced Photodetector on an Ultra-Low Loss Silicon Nitride Delay Line Interferometer
Rahul Chawlani, Fatemehsadat Tabatabaei, Mark W. Harrington +7
Thin core silicon nitride photonics enables ultra-low loss, CMOS foundry compatible integration that supports wavelengths from the visible to shortwave infrared. Applications that…
Blue to Near-IR Integrated PZT Silicon Nitride Modulators for Quantum and Atomic Applications
Nick Montifiore, Andrei Isichenko, Nitesh Chauhan +8
Modulation and control of lasers and optical signals is necessary for trapped-ion and cold neutral atom quantum systems. Given the diversity of atomic species, experimental modalit…
Sub-Doppler rubidium atom cooling using a programmable agile integrated PZT-on-SiN resonator
Andrei Isichenko, Steven Carpenter, Nick Montifiore +12
Programmability and precise control of laser frequency are essential for quantum experiments and applications such as atomic clocks, quantum computers, and cold-atom sensors. Curre…
Photonic chip-based optical frequency division with PZT-integrated soliton microcombs
Ruxuan Liu, Mark W. Harrington, Shuman Sun +15
Optical frequency division (OFD) produces low-noise microwave and millimeter-wave signals by transferring the exceptional stability of optical references to electronic frequency do…
Laser intensity noise suppression for space-borne gravitational wave mission
Fan Li, Xin Shang, Zhenglei Ma +7
Laser intensity noise is a main limitation of measurement and sensing mission represented by gravitational wave detection. We develop a noise decomposition model and design the cor…
Sub-100 Hz Intrinsic Linewidth 852 nm Silicon Nitride External Cavity Laser
Hani Nejadriahi, Eric Kittlaus, Debapam Bose +8
We demonstrate an external cavity laser with intrinsic linewidth below 100 Hz around an operating wavelength of 852 nm, selected for its relevance to laser cooling and manipulation…
