Optical coherence tomography imaging and noise characterization based on 1-μm microresonator frequency combs

APL Photonics
Spectral-domain optical coherence tomography is a pervasive, non-invasive, in vivo biomedical imaging platform that currently utilizes incoherent broadband superluminescent diodes to generate interferograms from which depth and structural information are

Visible Octave Frequency Combs in Silicon Nitride Nanophotonic Waveguides Driven by Ti:Sapphire Lasers

Laser &Photonics Reviews, EarlyView.
Chip‐based frequency combs are usually pumped from telecom wavelengths, far from the visible. This work instead pumps close to the visible with a Ti:sapphire laser ‐ the source behind the original optical frequency combs and now becoming chip‐integrable‐ and lets silicon‐nitride waveguides convert it into efficient, octave‐spanning visible‐to‐infrared ...

A Fully‐Connected Chip‐Integrated Reconfigurable Mode‐Pairing Quantum Key Distribution Network

Laser &Photonics Reviews, EarlyView.
This work constructs a fully connected reconfigurable chip‐integrated quantum key distribution network via the mode‐pairing protocol. Hybrid ECL and WSS chips cut wavelength and port overhead, realizing arbitrary‐user key sharing with merely two wavelengths.

Entangled Dual-Comb Spectroscopy

Physical Review X
Optical frequency combs have emerged as a cornerstone for a wide range of areas, including spectroscopy, ranging, optical clocks, time and frequency transfer, waveform synthesis, and communications. However, quantum-mechanical fluctuations of the optical

Color Symmetry Breaking in a Nonlinear Optical Microresonator

Laser &Photonics Reviews, EarlyView.
A two‐color pump drives an integrated microring resonator into spontaneous color symmetry breaking mediated by the nonlinear Kerr effect. Above threshold, one optical color becomes spontaneously dominant while the other is submissive, with the selected output state emerging randomly. These results establish a new form of symmetry breaking in integrated

Dual-pump Kerr Micro-cavity Optical Frequency Comb with varying FSR spacing

, 2016
In this paper, we demonstrate a novel dual-pump approach to generate robust optical frequency comb with varying free spectral range (FSR) spacing in a CMOS-compatible high-Q micro-ring resonator (MRR).

Phase noise characterization of injection locked semiconductor lasers to a 250 MHz optical frequency comb

Two lasers are simultaneously injection locked to the same comb mode and the injection locking quality is assessed in terms of phase noise and phase variance (1 kHz-10 MHz) for various injected ...

Parallel Vector Processing in Optical Computing With Jacobi Time‐Wave Packets

Laser &Photonics Reviews, EarlyView.
Functionality of a single neuron and state of the art photonic acceleration with a Mach‐Zehnder‐interferometer (MZI) mesh (i), a crossbar array (ii) and a micro ring resonator (MRR) array (iii). In the proposed Jacobi time‐wave packet approach (iv) a single modulator (here a ring modulator) is performing the whole scalar vector product in a single ...
