Optimality analysis of train platforming and routing with different interlocking modes
Communications in Transportation Research, 2022 The train platforming and routing (TPR) problem is to decide train operations within stations after the network-wise train schedules are determined. A feasible TPR plan requires both platform and route conflict-free, where the avoidance of route conflict

1.55 µm AlGaInAs/InP sampled grating laser diodes for mode-locking at THz frequencies [PDF]
, 2018 We report mode locking in lasers integrated with semiconductor optical amplifiers, using either conventional or phase shifted sampled grating distributed Bragg reflectors(DBRs).

Laser mode-locking with saturable absorbers [PDF]
, 1967 In this paper we describe a mode-locked laser in terms of traveling pulses of light. We show that the energy absorbed by a saturable absorber is a minimum if the pulselength is a minimum, and that two pulses are essentially as favorable as one if they ...

Saturable absorption properties and femtosecond mode-locking application of titanium trisulfide
, 2020 Titanium trisulfide (TiS3) is regarded as a candidate material for optoelectronic devices and nano-transistors due to its photoresponse. However, its nonlinear optical response in a mode-locked laser is yet to be investigated.

Irrational mode locking in quasiperiodic systems [PDF]
, 2007 A model for ac-driven systems, based on the Tang-Wiesenfeld-Bak-Coppersmith-Littlewood automaton for an elastic medium, exhibits mode-locked steps with frequencies that are irrational multiples of the drive frequency, when the pinning is spatially ...

Injection dynamics in spin-wave active ring oscillator (SWARO) [PDF]
AIP AdvancesWe investigated injection locking in spin-wave active ring oscillators (SWAROs) operating in the multi-mode regime. By applying external RF signals with varying frequency and power, we identified the locking behavior of individual modes and extracted the

Spatio-Temporal Mode-locking in Quadratic Nonlinear Media
, 2020 A new theoretical model is developed to characterize spatio-temporal mode-locking (ML) in quadratic nonlinear media. The model is based on the two-dimensional nonlinear Schr\"odinger equation with coupling to a mean term (NLSM) and constructed as an ...

PT-symmetric mode-locking [PDF]
Optics Letters, 2016 Parity-time (PT) symmetry is one of the most important accomplishments in optics over the past decade. Here the concept of PT mode-locking (ML) of a laser is introduced, in which active phase-locking of cavity axial modes is realized by asymmetric mode coupling in a complex time crystal. PT ML shows a transition from single- to double-pulse emission as

IEEE Photonics Journal, 2013 The wavelength tunability of all-normal-dispersion (ANDi) ytterbium (Yb)-doped mode-locked fiber laser is experimentally investigated, where the laser is mode-locked by nonlinear polarization rotation and the wavelength is adjusted by an intracavity ...
