Vernier-assisted mode-selective PT symmetry in optoelectronic oscillators
Gazi M. Hasan, Abhijit Banerjee, Trevor J. Hall
Mode-selective PT-symmetry is the manifestation of Vernier-assisted cross-injection between oscillators with unequal delays. PT-symmetry has been proposed as a mechanism for achiev…

PT-symmetric time delay oscillator modelling beyond the weak coupling limit via a scattering matrix formulation
Abhijit Banerjee, Trevor J. Hall
Parity-time (PT) symmetry in time-delay oscillators such as lasers and optoelectronic oscillators provides a potential route to enhanced spectral purity, including reduced phase no…

Multiscale phase dynamics and phase kinks in injection-locked optoelectronic oscillators with large delay
Abhijit Banerjee, Trevor J. Hall
Injection locking of optoelectronic oscillators (OEOs) with large delay gives rise to phase dynamics that lie beyond the scope of classical single mode locking theory, including th…
