Nanophotonic oscillators for laser conversion beyond an octave

February 11, 2025
Author(s)
Grant Brodnik, Haixin Liu, David Carlson, Jennifer Black, Scott Papp
Many uses of lasers place the highest importance on access to specific wavelength bands. For example, mobilizing optical-atomic clocks for a leap in sensing requires compact lasers at frequencies spread across the visible and near infrared. Integrated

Noiseless Loss Suppression for Entanglement Distribution

December 2, 2024
Author(s)
Cory Nunn, Daniel Jones, Todd Pittman, Brian Kirby
Recent work by Mičuda et al. [Phys. Rev. Lett 109, 180503 (2012)] suggests that pairing noiseless amplification with noiseless attenuation can conditionally suppress loss terms in the direct transmission of quantum states. Here we extend this work to

Kinetic inductance current sensor for visible to near-infrared wavelength transition-edge sensor readout

We synthesized and studied color centers on silicon-on-insulator wafers with photoluminescence mapping and spectroscopy, and fabricated silicon W- and G- color center LEDs towards electrically-pumped single photon sources.

Phase stabilization with single photon detection for quantum networks

October 29, 2024

Jabir Marakkarakath Vadakkepurayil, Daehyun Ahn, FNU Nur Fajar Rizqi Annafianto, Ivan Burenkov, Abdella Battou, Sergey Polyakov
Maintaining stable phases in interferometric systems and optical links is pivotal for the functionality of diverse quantum communication protocols. However, conventional phase stabilization methods use classical optical signals that may corrupt quantum

Emerging integrated laser technologies in the visible and short near-infrared

Xiyuan Lu, Lin Chang, Minh Tran, Tin Komljenovic, John Bowers, Kartik Srinivasan
Applications in timekeeping, quantum sensing and quantum computing have sparked growing demand for high-performance photonic integrated circuit (PIC) lasers at visible and short near-infrared wavelengths between 400 nm and 1,000 nm. This Review summarizes

Rydberg states of alkali atoms in atomic vapor as SI-traceable field probes and communications receivers

September 16, 2024
Author(s)
Noah Schlossberger, Samuel Berweger, Nikunjkumar Prajapati, Andrew Rotunno, Alexandra Artusio-Glimpse, Matthew Simons, Abrar Sheikh, Eric Norrgard, Stephen Eckel, Christopher Holloway
Rydberg states of alkali atoms are highly sensitive to electric fields because their electron wavefunction has a large spatial extent, leading to large polarizabilities for static fields and large transition dipole moments for time-varying fields. Over the

Foundry manufacturing of octave-spanning microcombs

September 6, 2024

Jizhao Zang, Haixin Liu, Travis Briles, Scott Papp
Soliton microcombs provide a chip-based, octave-spanning source for self-referencing and optical metrology. We use a silicon nitride integrated photonics foundry to manufacture 280 single-chip solutions of octave-spanning microcombs on a wafer. By group
