Tunable transform-limited pulse generation using self-injection locking of an FP laser [PDF]

open access: yes, 1993
Wavelength-tunable, near transform-limited pulses have been generated using a Fabry-Perot laser diode coupled to a fiber loop containing a fiber Fabry-Perot resonator (FFPR) and a polarization controller.

An 18.8–33.9 GHz, 2.26 mW Current-Reuse Injection-Locked Frequency Divider for Radar Sensor Applications

open access: yesSensors, 2021
An 18.8–33.9 GHz, 2.26 mW current-reuse (CR) injection-locked frequency divider (ILFD) for radar sensor applications is presented in this paper. A fourth-order resonator is designed using a transformer with a distributed inductor for wideband operating ...

Injection Locking of a Semiconductor Double Quantum Dot Micromaser

open access: yes, 2015
Emission linewidth is an important figure of merit for masers and lasers. We recently demonstrated a semiconductor double quantum dot (DQD) micromaser where photons are generated through single electron tunneling events.

Multiple RF carrier distribution in a hybrid radio/fiber system employing a self-pulsating laser diode transmitter [PDF]

open access: yes, 2002
A self-pulsating laser diode is used to generate a multicarrier microwave optical signal for use in a hybrid radio/fiber system. The self-pulsation frequency of the laser is controlled by external light injection, and can be varied between 14-24 GHz. The

Self-Injection Locking of a Distributed Feedback Laser Diode Using a High-Finesse Fabry-Perot Microcavity

open access: yesApplied Sciences, 2019
Optical microcavities have been widely used in nonlinear optics, quantum optics, and laser technologies. Here we demonstrate the self-injection locking of a distributed feedback diode laser using home-made high-finesse Fabry-Perot microcavity.

Extended L-Band InAs/InP Quantum-Dash Laser in Millimeter-Wave Applications

open access: yesPhotonics, 2021
We report on the generation and transmission of a millimeter-wave (MMW) signal with a frequency of 28 GHz by employing an InAs/InP quantum-dash dual-wavelength laser diode (QD-DWL) emitting in the ~1610 nm extended L-band window.

Boolean Computation Using Self-Sustaining Nonlinear Oscillators

open access: yes, 2015
Self-sustaining nonlinear oscillators of practically any type can function as latches and registers if Boolean logic states are represented physically as the phase of oscillatory signals.

Energy boost in laser wakefield accelerators using sharp density transitions [PDF]

open access: yes, 2015
The energy gain in laser wakefield accelerators is limited by dephasing between the driving laser pulse and the highly relativistic electrons in its wake.
