Self-Injection Locking of a Gain-Switched Laser Diode

We experimentally observe a self-injection locking regime of the gain-switched laser to a high-Q optical microresonator. We reveal that the comb generated by the gain-switched laser experiences a dramatic reduction of comb-teeth linewidths in this regime. ...

Degradation study on molecules released from laser-based jet injector

Christophe Moser, Jan Krizek, Barbora Lavickova

Development of needle-free methods to administer injectable therapeutics has been researched for a few decades. We focused our attention on a laser-based jet injection technique where the liquid-jet actuation mechanism is based on optical cavitation. This ...

Gain-switched semiconductor laser driven soliton microcombs

Tobias Kippenberg, Junqiu Liu, Erwan Guillaume Albert Lucas, Wenle Weng, Jijun He

Dissipative Kerr soliton generation using self-injection-locked III-V lasers has enabled fully integrated hybrid microcombs that operate in turnkey mode and can access microwave repetition rates. Yet, continuous-wave-driven soliton microcombs exhibit low e ...

System and method for high beam quality pulse generation in mode-locked multimode fiber lasers

Demetri Psaltis, Christophe Moser, Ugur Tegin

A system and method to generate ultrashort high beam quality pulses from spatio- temporally mode-locked multimode fiber laser are described. The invention relies on engineering the intra-cavity pulse propagation in a multimode laser cavity to shape the spa ...

n-photon blockade with an n-photon parametric drive

Fabrizio Minganti, Wei Qin

We propose a mechanism to engineer an n-photon blockade in a nonlinear cavity with an n-photon parametric drive lambda(adagger n + an). When an n-photon-excitation resonance condition is satisfied, the presence of n photons in the cavity suppress ...

Kilowatt-range Picosecond Switching Based on Microplasma Devices

Elison de Nazareth Matioli, Remco Franciscus Peter van Erp, Armin Jafari

Plasma formation in micro- and nano-scales enables an ultrahigh-dv/dt picosecond switching in an integrated circuit form factor. Such on-chip plasma devices could provide a transformative approach to achieving high-power levels at very high frequencies, fa ...

Liouvillian spectral collapse in the Scully-Lamb laser model

Fabrizio Minganti

Phase transitions of thermal systems and the laser threshold were first connected more than forty years ago. Despite the nonequilibrium nature of the laser, the Landau theory of thermal phase transitions, applied directly to the Scully-Lamb laser model (SL ...

Collective dynamics in nonlinear resonators coupled in spatial and synthetic dimensions

Tobias Kippenberg, Aleksandr Tusnin, Alexey Tikan

We theoretically investigate chaotic and stable structures in coupled-resonator chains and synthetic frequency dimension influenced by Kerr nonlinearity, thereby bringing insights in the emerging field of soliton generation in chains and lattices of high-Q ...

Generating optical pulses via a soliton state of an optical microresonator coupled with a chip based semiconductor laser

Tobias Kippenberg, Hairun Guo, Arslan Sajid Raja

A light pulse source (100), being adapted for generating repetitive optical pulses (1), comprises a continuous wave cw laser device (10) being arranged for providing cw laser light (2), an optical waveguide (20) being optically coupled with the cw laser de ...

Self-Blinking Dyes Unlock High-Order and Multiplane Super-Resolution Optical Fluctuation Imaging

Theo Lasser, Aleksandra Radenovic, Tomas Lukes

Most diffraction-unlimited super-resolution imaging critically depends on the switching of fluorophores between at least two states, often induced using intense laser light and specialized buffers or UV radiation. Recently, so-called self-blinking dyes tha ...
