High-energy picosecond pulses with a single spatial mode from a passively mode-locked, broad-area semiconductor laser
Mallachi-Elia Meller, Leon Bello, Idan Parshani +2
We present a mode-locked semiconductor laser oscillator that emits few picosecond pulses (5-8ps at 379MHz repetition) with record peak power (112W) and pulse energy (0.5nJ) directl…
Quantifying the Expressive Capacity of Quantum Systems: Fundamental Limits and Eigentasks
Fangjun Hu, Gerasimos Angelatos, Saeed A. Khan +6
The expressive capacity of quantum systems for machine learning is limited by quantum sampling noise incurred during measurement. Although it is generally believed that noise limit…
Soft aperture spatial filtering: 1.5W in a single spatial mode from a highly multi-mode laser diode in an external cavity
Mallachi-Elia Meller, Idan Parshani, Leon Bello +3
Broad area laser diodes are attractive for the high optical power they can produce. Unfortunately, this high power normally comes at the cost of severely reduced spatial coherence…
Complete reconstruction of the space-time dynamics in a Kerr-lens mode-locked laser
Idan Parshani, Leon Bello, Mallachi-Elia Meller +1
We present a complete numerical analysis and simulation of the full spatio-temporal dynamics of Kerr-lens mode-locking (KLM) in a laser on all time-scales. The KLM dynamics, which…
Passive symmetry breaking of the space-time propagation in cavity dissipative solitons
Idan Parshani, Leon Bello, Mallachi-Elia Meller +1
Dissipative solitons are fundamental wave-pulses that preserve their form in the presence of periodic loss and gain. The canonical realization of dissipative solitons is Kerr-lens…
Augmenting the Sensing Performance of Entangled Photon Pairs through Asymmetry
Yoad Michael, Isaac Jonas, Leon Bello +4
We analyze theoretically and experimentally cases of asymmetric detection, stimulation, and loss within a quantum nonlinear interferometer of entangled pairs. We show that the visi…
One-particle and two-particle visibilities in bipartite entangled Gaussian states
Danko Georgiev, Leon Bello, Avishy Carmi +1
Complementarity between one- and two-particle visibility in discrete systems can be extended to bipartite quantum-entangled Gaussian states. The meaning of the two-particle visibil…
Can nonlinear parametric oscillators solve random Ising models?
Marcello Calvanese Strinati, Leon Bello, Emanuele G. Dalla Torre +1
We study large networks of parametric oscillators as heuristic solvers of random Ising models. In these networks, known as coherent Ising machines, the model to be solved is encode…
Broadband complex two-mode quadratures for quantum optics
Leon Bello, Yoad Michael, Michael Rosenbluh +2
In their seminal paper, Caves and Schumaker presented a new formalism for quantum optics, intended to serve as a building block for describing two-photon processes, in terms of new…
Pairwise mode-locking in dynamically-coupled parametric oscillators
Leon Bello, Marcello Calvanese Strinati, Shai Ben-Ami +1
Mode locking in lasers is a collective effect, where due to a weak coupling a large number of frequency modes lock their phases to oscillate in unison, forming an ultrashort pulse…
The diffractive saturable loss mechanism in Kerr-lens mode-locked lasers: direct observation and simulation
Idan Parshani, Leon Bello, Mallachi-Elia Meller +1
Passive mode-locking critically relies on a saturable loss mechanism to form ultrashort pulses. However, in Kerr-lens mode-locking (KLM), no actual absorption takes place, but rath…
Coherent dynamics in frustrated coupled parametric oscillators
Marcello Calvanese Strinati, Igal Aharonovich, Shai Ben-Ami +3
We explore the coherent dynamics in a small network of three coupled parametric oscillators and demonstrate the effect of frustration on the persistent beating between them. Since…
Theory of coupled parametric oscillators beyond coupled Ising spins
Marcello Calvanese Strinati, Leon Bello, Avi Pe'er +1
Periodically driven parametric oscillators offer a convenient way to simulate classical Ising spins. When many parametric oscillators are coupled dissipatively, they can be analogo…
Persistent coherent beating in coupled parametric oscillators
Leon Bello, Marcello Calvanese Strinati, Emanuele G. Dalla Torre +1
Coupled parametric oscillators were recently employed as simulators of artificial Ising networks, with the potential to solve computationally hard minimization problems. We demonst…
Squeezing-enhanced Raman spectroscopy
Yoad Michael, Leon Bello, Michael Rosenbluh +1
The sensitivity of classical Raman spectroscopy methods, such as Coherent Anti-Stokes Raman spectroscopy (CARS) or Stimulated Raman spectroscopy (SRS), is ultimately limited by sho…
Lifting the Bandwidth Limit of Optical Homodyne Measurement
Yaakov Shaked, Yoad Michael, Rafi Z. Vered +3
Homodyne measurement is a corner-stone of quantum optics. It measures the fundamental variables of quantum electrodynamics - the quadratures of light, which represent the cosine-wa…
